# News from Mathnasium of Broomfield South

Sep 16, 2018

Common Core Curriculum was adopted by 42 states after its debut in 2002. The state of Colorado adopted it in 2010 and the Colorado Department of Education adapted the national standard with local aspects including financial literacy, 21st century skills, and more. Jeffco Public Schools, BVSD, Adams 12, Westminster 50, and others local school districts follow these standards today. The standards for 2nd grade math have multiple goals for a student to meet by year end. There are four key areas for second graders to master:

1. Deepen understanding of the base-ten system. This includes both counting in groups and building understanding of place value. At this stage, this means fluency counting in 5’s and 10’s as well as multiple of hundreds, tens and ones. Students must also understand the proportional relationship between these units. Base-10 place value understanding to 1,000 means 2nd grade students must know the difference between the hundreds, tens, and ones place.
2. Common core addition and subtraction in grade 2 math is limited within 100, with operations mainly up to 20. Several models for addition and subtraction are used and students must learn to use them efficiently and accurately. They must understand the properties of each operation, for example that addition is not order specific while subtraction is, like how both 3+2 and 2+3 equal five, but that 3-2 and 2-3 are not equivalent.  Beyond understanding written methods, students must mentally calculate tens and hundreds, beginning to build a base-10 mental math skillset.
3. Measurement is another pillar of second grade common core math standards. Students will use rulers and other measurement tools to measure in both inches and centimeters. The goal is understanding that as units decrease in size, the iteration of units increases.
4. The foundations of Geometry begin in second grade and form another key 2nd grade math standard. Second grade math students analyze shapes by examining sides and angles and mix and combine them to form new shapes. The goal is to build their understanding of area, volume, congruence, similarity, and symmetry for future application in later grades.

2nd Grade math is significantly more rigorous than 1st grade, and if students begin to struggle or get bored they start to develop a negative mindset about math that will set them back. Unfortunately, in-class and self-guided online instruction don’t go far enough to ensure kids stay on track, they often need direct guidance from a trained tutor.

Here at Mathnasium of Broomfield South, we are well equipped to help second graders meet and exceed these standards. Our numerical fluency curriculum focuses on building number sense, the ability to effortlessly compute addition and subtraction facts in the single and double digits. Computation up to 100 involves carrying, which means understanding the complements of 10 is crucial. With young students’ energy and enthusiasm in teaching matters, and so Mathnasium mixes its curriculum with math games involving cards, dice, and other manipulatives that keep it fun and on task. Understanding the units of measure is also a part of the program, as well as building their understanding of shapes with lots of visuals. We have a system of rewards so that when kids complete a page they get a reward card punched and save them to trade for prizes from the prize cabinet. A final mastery check page concludes our lessons, and when students complete them with no errors, they get to spin a prize wheel and win extra star punches and rewards that keep them motivated and having fun.

Our center offers a variety of enrollment length options to meet your goals and budget. Enrollment for 2nd Graders can be on a “session” or on an unlimited basis. We recommend 2-3 times a week attendance for fastest math skill growth, but our attendance is flexible and drop-in so more or less is possible as well.  All students begin with our comprehensive assessment, giving you a clear picture of your students’ math skills and allowing us to build a customized learning plan.
