While math may not be his favorite subject, he has always greatly appreciated the role of mathematics as a way of representing the complicated reality of the world. He has always enjoyed helping others, especially with math, from his siblings, to his fellow classmates, and others in general.

Ellen Shaler

Ellen is originally from Detroit. Upon earning her teaching credential at the University of Michigan, she taught preschool in Ann Arbor for two years, then moved to California. She spent the next 32 years teaching upper elementary, the last 25 of which were in OUSD. For 10 years, she team-taught 4th and 5th grades, as the Math and Science half of the teaching partnership. Ellen worked hard to impart her passion for patterns, logic, and mental math, by helping her students develop number sense, build their confidence, and promote a love of numbers. After retiring in 2017, Ellen started volunteering at Summit Hospital, making home-cooked meals for neighbors, and working at Mathnasium. She loves to cook, travel, take walks, organize gatherings, and read. She still quotes her favorite high school Math teacher: "Math is good and good for ya. We love Math!"

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
