Suzie Shride, Center Director 

Hello! I am the Center Director at Mathnasium of Littleton. I am a retired classroom teacher with a Masters Degree in Education and I am Master Certified through Mathnasium University. That means I have more than 2500 hours of training in the Mathnasium Method. I know first-hand the Mathnasium Method works because my teenaged daughter went from hating math and declaring she "just didn't have a math brain" in 6th grade to math being her best academic subject in high school and her saying, emphatically, "Mom! I don’t need help with math! I am good at math!" and her 100% scores on math tests prove her right!

I am in the process of writing about my 20 plus years of world-wide climbing and outdoor adventures in an award-winning Young Adult series, Lucy Dakota: Adventures of a Modern Explorer. My debut novel, Rocky Mountain Beginnings  won the Colorado Book Award for best YA novel in 2011.  The second book in the series, Journey to Nepal, is in the works. In July 2014 I hiked 96 miles along the West Highland Way in Scotland with my sister, Allison, and I am looking forward to our next trek, perhaps the Tour du Mont Blanc Circuit in 2017 or hiking in Norway?!

I am one of those kids who had to work at math in high school and college, and despite earning straight A's, I was a finger counter. I understand the pressure kids face to succeed at math. My wish is for every child who comes to our center to reach a point where math makes sense to them and I promise to give every student that passes through our doors the foundation they need to understand math! Who knows? They might even become crazy about math!

Fun Fact: I have climbed to the base camp of the world's highest and fifth highest mountains - Everest & Makalu!

Hobbies: Hiking, gardening, travel, animals

Favorite Number: 18 - it's my birthday and has always been my lucky number. In numerology it also has special meaning to me as it adds to 9 which is my favorite number for mathematics.

 

Larry Martinek, Creator of the Mathnasium Method

Larry Martinek, Chief Instructional Officer, Developer of Mathnasium Program. 

Larry has spent his entire career finding a better way to teach math. From inner city to public schools, to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed curriculum, teaching strategies, and teaching materials designed to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting students' ability to “do” math, thereby increasing students' math scores and feeling of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculas ever produced for teaching math.

While Larry is not an Instructor at our Center, he conducts many of the training sessions our instructors and center director attend, hosts special math afternoons at our annual Mathnasium convention and is a valuable asset we can call on to ask about specific students' scenarios for guidance and advice. This has helped to make visits more productive and enjoyable for many of our students. 


The AMAZING team of instructors at Mathnasium of Littleton!


Monica Rodeghiero, Assistant Center Director

Miss Monica is an expert on middle school kids. As a Lakewood resident, she loves the Colorado lifestyle. Monica graduated as valedictorian from Alameda High School. She went on to get her BS in Mathematics and her teaching certificate. She then earned a Master’s Degree in Middle School Education while teaching. For 25 years, she taught adolescents aged 11-14 in Jefferson County Public Schools. Twenty-four of the years were in a middle school setting and one year was as a sixth grade teacher in an elementary school setting.  When not teaching at Mathnasium, Miss Monica likes to race cars and she is a true Trekkie (if you don't know what this is - ask her).

Favorite Number: 42 because according to the Hitchhiker's Guide to the Galaxy book and movie it is the answer to Life, the Universe and Everything!

I love Mathnasium because . . .  I have never worked with a greater, more passionate group of instructors. I also love all of our students and the opportunity to work one-on-one with them. It gives me a chance to see them grow both as a math student and as an individual.

Your Story – why did you come to work at Mathnasium?  I left teaching middle school after 25 years because it was becoming test driven and less personal.  I found that after a couple of years away, I missed working with the students.  I was blessed to have met Suzie at a networking group and she asked, and I finally said yes, for me to take the test for being an instructor at Mathnasium.  And I couldn’t be any happier that she did and she hired me.  I LOVE working at Mathnasium of Littleton.


Zach Chaney, Lead Instructor 

Hello, my name is Zach. I’m currently a junior at the Colorado School of Mines pursuing a degree in mathematics. Last fall semester I took five math courses including an independent study course in Combinatorial Set Theory! I’m also finalizing a research paper on Ramsey theory that we will hopefully submit for publication later this year. I’ve been interested in math for most of my life. In fact, I remember back in elementary school I became quite fascinated with figurate numbers. My teacher at the time encouraged this curiosity and helped me develop a formula for the triangular numbers. I later discovered formulas for squares, pentagons, and eventually a general formula for regular polygonal numbers. The encouragement that I’ve received then and over the years has helped push me toward my pursuit of math thus far. This is why I feel like it is so important to help encourage students so they can gain confidence and explore their own interests. I hope to continue my education through graduate school and one day pursue a career in academia. It’s my dream to share the beauty and awe that I have for math to anyone willing to listen.

Favorite Number: 8128 because it was the fourth and largest perfect number known to the ancient Greeks. It took mathematicians over 1400 years to find the next perfect number, and it’s still left unproven whether or not there exists infinitely many perfect numbers.

I love Mathnasium because… it encourages every student to apply themself and breeds mathematical curiosity.

Favorite Math Topic and Why: Set Theory because it formalizes the foundation of mathematics and can prove the consistency of arithmetic.


Reyna Felipa, Instructor

Hi, my name is Reyna Felipa! I am a senior at D'Evelyn Jr./Sr. High School. I love animals and have many pets including 2 Labradoodles, 2 cats and a parakeet.  I also love kids and enjoy having fun with them and teaching them a variety of things including math! I love to play many sports such as volleyball, gymnastics, and tennis. Music is also one of my biggest passions and I've been playing saxophone for the past 10 years! Currently my favorite subject in school is math but it didn't start out that way. Math actually used to be my least favorite and most difficult subject so I attended Mathnasium in Parker over two summers and ever since then I have started appreciating and enjoying math more which is what I hope I can do for kids at  Mathnasium of Littleton!

Favorite Numbers:  My favorite numbers are 7 and 9 because they were my class numbers in elementary school.

Fun Fact: I am half Peruvian and have hiked to Machu Picchu 3 times.

Hobbies: I really love photography which is what I want to major in at college.

 I love Mathnasium because . . . I have so many of the students who I am friends with and I love seeing them, helping them with math and getting hugs every day!


Mr. Fleck, Instructor

Hi! I am Carl (Van) Fleckenstine, “Mr. Fleck." I am  a retired Internal Audit Director, Certified Public Accountant, and Certified Internal Auditor.  Prior to my career as a CPA and Internal Auditor, I taught High School Mathematics and Physics.  After retiring, I have been active as a Math Fellow in the Denver Public Schools tutoring math at the High School and Middle School levels. I hold a Colorado Alternative Teacher Licensing Program Eligibility Certificate in Secondary Mathematics.  I am also a volunteer with Jefferson County Open Space and am active with the Colorado Senior Old Boys Rugby Club. I became a grandfather for the first time last year and my wife, Deb, and I enjoy hiking as often as we can! I am excited about tutoring young people in Mathematics at Mathnasium of Littleton and enjoy helping them fully realize their math potential.

Favorite Number:  7 because it is my birthday - July 7 (and it is Abby's birthday, too).

Fun Fact: I just became a grandfather!

I love Mathnasium because . . . . we're helping students.


Danny Terry III, Instructor

Hi, I'm Danny! I am a senior at D'Evelyn Jr/Sr High School. I enjoy working at Mathnasium because I've always had an affinity for math and I enjoy teaching it. Math is very methodical for me and every part of it makes sense. It's because of that outlook about math that I think it is very fun to teach children even just basic math; because teaching them simple addition and subtraction may seem easy to me but it means everything for them and these are the building blocks upon which the rest of their math career will be built. My calculus teacher, Cindy Cannon, from my sophomore year in high school, taught me a different way to approach math than I had ever done before. She hated memorization and she was all about knowing WHY things were the way they were. Before then I had had all of my teachers tell me to memorize this formula or that this equals this but she changed all of that and made the whole reason of why math is what it is really make sense. Along with that, she made math incredibly fun to learn and to teach and she really made me want to continue learning more math.  

Favorite Number and Why:
My favorite number is 64 because it is a perfect square, a perfect cube, and the addition of the two digits equals 10. It's a mathematically nice number all around.

In 5 years I will be  . . . . attending medical school and learning to become a plastic surgeon. I've always wanted to be a plastic surgeon to help people who have any type of physical issue they'd like fixed.

I love Mathnasium because . . . . . I love the Mathnasium way of teaching. We teach with a very methodical process and kids always seem to understand and even enjoy our way of teaching. It's always so gratifying to help a struggling kid finally understand a topic and really grasp it.

Fun Fact: Something really nerdy I do when I run long distances is I just do math in my head the whole time. I'll think to myself things like, "If I run at 7 minute miles then my 5 miles will take me 35 minutes." And during the whole run I'll just add basic numbers in my head.


Joe Moser, Instructor

Hi, my name is Joe. I am currently a junior at D’Evelyn Junior/Senior High School. I love math because I love working with numbers and I love that math builds on itself and every concept you learn is useful. I have always loved math because I had fantastic teachers who taught me the importance of math. I also really enjoy science because you can apply topics you have learned in math to real world applications. I’ve been running cross-country for two years now because it is a great way to relax after school and clear your head of stress. I really look forward to inspiring kid to enjoy math at Mathnasium.

I love Mathnasium because … It allows kids to learn how to do math in a manner that is more intuitive than a normal classroom

Hobbies: I enjoy running, playing basketball, and video games

Why did you come to work at Mathnasium? I found out about Mathnasium through my sister, Abby, and I thought it was such a great idea to teach kids in a way that made sense to them rather than lectures in a classroom. So, I was very interested in becoming an instructor because I believe math is a vital concept to understand and I want to help as many people as possible enjoy math.


Tyler Yeaman, Instructor

Hey there, I’m Tyler. I recently graduated from Cal Poly San Luis Obispo with a BS in Mechanical Engineering. Teaching and tutoring has always been something I’ve enjoyed. For some reason, I’ve always had a knack for math (as hard as it can be at times) and even more, I am passionate helping others learn the subject. Math hasn’t always come easy for me; I constantly had to study and seek help. However, once I finally understood and overcame my struggles, it was one of the most rewarding feelings. It is my goal to help others reach their math potential and change their dislike of math into something more positive. Outside of Mathnasium, I love exercising, mountain climbing, camping, and skiing.  

In 5 years I will be  . . . .  working as a Mechanical Engineer doing work that I love and am passionate about. Above all, I will work to have a positive impact on the world around me.

I love Mathnasium because . . . . . I love Mathnasium because they teach efficient and intuitive ways to learn and remember math topics. The Mathnasium Method allows students to learn without feeling anxious to get the right answer and understand the material immediately. The instructors act as mentors to their students and they create an environment conducive to learning in a fun and relaxed way.

Fun Fact: I am a native of Colorado and have the personal goal of peaking all of Colorado’s 58 14,000 foot mountains. So far, I have peaked 45 of the 58 mountains!

Why did you come to work at Mathnasium? I recently graduated from Cal Poly San Luis Obispo with a degree in Mechanical Engineering. I came to work at Mathnasium because I enjoy teaching and tutoring, and I wanted to spend some time after graduation doing something I enjoyed but was still productive. It is really rewarding working with young students learning math.


Mary Jane Sliter, Instructor 

I am currently in my seventh year as a Geometry and Advanced Algebra teacher at a high school for Denver Public Schools.  I  earned my Master’s degree last spring and was made a team lead last year. I am currently working on a second Master's degree in mathematics!  I have experience volunteering in middle school and high school classrooms, as well as over 15 years of experience working with youth.  I enjoy seeing students build confidence in themselves and in math.  The most rewarding moments are when a student breaks down barriers and realizes of what they are capable.  My first child, William, turned one at the end of April this year! I will be back at Mathnasium 2-3 days per week this summer and fall!

Best Math Story: One of my most insecure students (during her freshman year), went on to become her class salutatorian (second highest ranking student in the class).

What is your dream? To travel to as many places as I can!

Favorite number? 4 - it is both my son's and my birthday.


Kaitee Weiman, Instructor   

Hi I'm Kaitee and I am currently a middle school teacher at Alameda International Jr./Sr. High School. I had a six year undergraduate career, spending 2 years at the University of Northern Colorado and 4 years at Metropolitan State University of Denver (MSU). I am a recent graduate from MSU, earning my secondary mathematics education degree in December of 2016. I'm so excited to finally be done with school so I can help build the leaders of tomorrow by being a classroom teacher and now a tutor at Mathnasium. It is vital to me that the students I work with know I believe in them and that they can do math. This is so important to me because I was once a student who struggled with mathematics and it really took a tole on my perception of myself. All it took for me was to have one teacher who showed me she believed in me by going above and beyond to help me understand. Her name was Ms. Halverson. I want to follow in Ms. Halverson's footsteps and show students  I believe in them and with perseverance and hard work they can be a rock star in math. Aside from giving back to my community by helping others better their math skills, I enjoy volunteering in the horse community and riding my horse Joker. During the summer Joker and I ride on a drill team together and we travel all around Colorado volunteering our time to perform in Rodeos.    

 I love Mathnasium because . . . It gives students opportunities to expand their knowledge of mathematics outside of the classroom. Mathnaisum helps students learn to self – regulate and self – justify answers to problems.  This in turn helps students gain confidence in math and beyond. Mathnasium is a place where students are able to grow and improve their math skills while also building character.

Hobbies: Riding horses, fishing, hiking, and watching sports.

Favorite math topic:  Statistics – I love stats because it is applicable to everyday life. Statistics is all about collecting and analyzing numerical data in large quantities. It’s fascinating to me that data can be studied and used to make educated predictions for the future. 


Peter Schmid, Instructor 

Hello, I'm Peter Schmid. I'm a junior at Colorado Academy. I love working with children, and I love math. Mathnasium is the perfect combination! I also love to build things (electronic and physical), code, and play drums, all of which rely heavily on mathematics. Math and science are my favorite subjects in school, and I am always curious to discover more about the world around me. The only thing more gratifying than making a discovery yourself is helping someone else make a discovery!

Favorite Number: 5,040 is my favorite number because it is Anti-prime. It is divisible by 60 different numbers, including 7!

Favorite Math Joke: There are three kinds of people in this world: People who can count, and people who can't.

Best Math Story:  In seventh grade, I had my favorite math teacher. He really ignited my love for math by making the class fun. Whenever our class had to specify if a number is positive or negative, we would call it "regular" instead of positive. Every time we did so, he came up with a different example of things that can be regular, and to show that numbers cannot. For example, "Numbers aren't gasoline, you can't choose between regular and premium!" or "Numbers aren't washing machines, they don't have regular and delicate settings!"


 Spencer Littel, Instructor 

Hi, I’m spencer. I’m a sophomore at Colorado School of Mines majoring in Applied Mathematics. I’ve lived in Colorado for my whole life, and love it here, however; I also love to travel. I’ve been to 7 other countries: Germany, Switzerland, France, Honduras, Mexico, Belize, and Senegal. My dream is to travel to different universities around the world to learn and teach math. When I’m not doing math, I enjoy playing soccer and music. I taught myself piano, guitar and drums. I’m not very good, but I enjoy playing none the less! I’m an only child, but I have 22 younger cousins. They all collectively taught me how to be patient. Math used to be my least favorite subject because I didn’t have good teachers, but I had one teacher in high school who changed my perception. I hope to be the inspiration to other kids that he was to me!

Favorite Number: i  because of the secret uses that come from imaginary numbers.

In 5 years I will be . . . . in grad school, hopefully, teaching math somewhere exotic!

I love Mathnasium because . . .we teach the intuition behind the concepts. That’s how math should be taught, but it unfortunately doesn’t get taught like that in most schools.

Favorite math topic: Linear algebra is my favorite topic because it opens up so many more doors for exploration and has beautifully simple ways to represent complex behaviors.


Yi Cai, Instructor 

Hello, I am Yi Cai. I am currently a junior at Colorado School of Mines majoring in Computational Applied Mathematics. I have always had a passion towards mathematics and helping people with it. I had experience in the past helping kids and my peer students with their math and realized that helping people get over their struggle was the most rewarding thing. I also like to travel: I have been to most of the states in the U.S. and most of the provinces in China.

Favorite Number: 9, because it is the greatest single-digit number.

Favorite Math Joke: An opinion without 3.1415926…… is just an onion.

Fun Fact: I play the bass guitar!

Hobbies: yoga, Zumba, badminton, hiking


Claire Madonna, Instructor 

Hello, I am Claire. I am currently a junior at D'Evelyn Jr. Sr. High School in Denver. I played on the girls soccer team at school and we won the first-ever state championship this past spring (2017). I joined Mathnasium because my older sister, Elise, has worked here for two years and really enjoys it. I want to help other kids understand math and enjoy it as much as I do.

Favorite Number: 11 because it was my soccer number when I was younger and I like the symmetrical look of the number itself. Also, it is very easy to multiply by.

Favorite Math Joke: Why did the polynomial plant die? Because its roots were imaginary!

I love Mathnasium because . . . it's a wonderful concept that can help kids enjoy math and succeed in school as well as throughout their everyday lives.

Fun Fact: I have been playing soccer for 3/4 of my life (12 years)!


Hannah Johannsson, Instructor 

I'm Hannah, and I'm a sophomore at the Colorado School of Mines in Golden. Before moving to Colorado for school, I worked at a Mathnasium in Oklahoma for over a year. I love my job because I have the ability to change a student's whole perspective on math. Every day, I help build students' confidence in their skills, which can make a world of difference. I personally struggled with math until I took my first algebra course. I found math class boring and hard to sit through, but that year, things turned around thanks to a fantastic teacher named Mrs. Clinger. She believed in order to succeed in mathematics, you have to approach it with a positive and determined mindset. We were not allowed to say things like "I'm so stupid" or "I suck at math" in her classroom. Successes were met with celebration, and failures were met with gentle correction, not patronization. She knew that when a student approached a problem thinking they weren't smart enough to complete it, the battle had already been lost. She built up my confidence first, and the math skills quickly followed. Today, I am pursuing a minor in mathematics, and I have come to adopt her philosophies with the students I work around. Over the past year, I have seen what a difference a little confidence can make in math education, and it brings me a lot of joy to be the one helping students find their confidence. When I'm not working or studying, I love to be outdoors hiking, skiing, and hammocking when weather permits. My bucket list includes items such as skydiving, climbing Kilimanjaro, backpacking across Iceland, and curing Alzheimer's.

Favorite Number: 13, partially because it's supposed to be unlucky but I have found it to be the opposite and partially because it is a fibbonacci number.

Fun Fact: I am bilingual. I speak both English and Icelandic fluently.

Favorite Math Joke: The classic: Why was 6 afraid of 7? Because 7 ate 9.


Kelly Ryan, Instructor

 Hi, I'm Kelly! I am a junior at Heritage High School. I love math and I love working with kids. Math is fun and I really enjoy doing it. I also enjoy helping people, so Mathnasium is a perfect fit. I am a dancer at Littleton Dance Academy and rehearse multiple hours each week, so I will only be working on Wednesdays during the school year.

Fun Fact: I have a pet gecko named Tumbleweed.

Favorite Math Joke:

PLAN

(P+L)(A+N)

PA+PN+LA+LN

Your plan has been foiled!

Favorite Math Topic: I really like anything algebra, like solving for x because that's when I first started to really enjoy math with one of my teachers who pushed me to work harder.


Hayley Black, Instructor

 Hi, I'm Hayley.

Favorite Number: If I had to choose, two would be my favorite number because it is both prime and even, and every even number is divisible by two.

In 5 years I will be  . . . . an architectural engineer.

Why did you come to work at Mathnasium? I wanted to work at Mathnasium because I wanted to have a job that involved something I enjoyed. I heard all my friends complain about their jobs working at restaurants and other stores, and I decided that I did not want that. As a result, I began to look for jobs that involved math that a high school student could apply for.

Elise is on leave from Mathnasium as she works on her degree at Colorado School of Mines. Hello, my name is Elise! I am a sophomore at Colorado School of Mines in Golden. My favorite subjects are math and science, so I have a blast working at Mathnasium! I, too, have worked at Mathnasium of Littleton for more than two years! I play tennis and run on the cross country team, and I love cross country skiing in the winter. I have two dogs (a lab and a miniature Australian shepherd) and a cat, and I play the guitar. I love being able to help other students through Mathnasium.

Favorite Number: 2 because it is a really nice number to work with and 2 + 2 = 22 which is rad!

In 5 years I will be . . . . hopefully graduated from the School of Mines

I love Mathnasium because . . . I really like that the program gives kids a second chance to learn they don't have to hate math. Also, it helps them realize how much math ability depends on attitude, not necessarily aptitude.

Favorite math topic:  Proportional reasoning because it is really applicable to real life and it is uncomplicated once you get the hang of it.

 

 Congratulations to Brett who has his first high school math class in DPS!

 

Math is fun with the great instructors at Mathnasium of Littleton!
