Math that makes sense

Arithmekit offers short video lessons and problem sets for students in Kindergarten through Grade 5, and for the families and educators who support them.

We build skill through four habits:

Model Count Question Explain

Your math tool kit

Each time students learn a strategy or model, such as a tape diagram, area model, or number bond, they add a tool to their math kit and learn when to reach for it.

Marie

Founder and CEO

As a former teacher and author of Eureka Math2, Marie found that the skills that move the math mastery needle for students come down to how well they can Model, Count, Question, and Explain.

What’s next

We hope to offer educator professional development and math night kits.
