I want to advocate for 20 minutes a day of math play, similar to how we advocate this time for reading for our most early learners. Promoting math play at an early age will hopefully lead to conceptual understanding, strong number sense, problem solving skills as well as strengthen their critical thinking. In addition, if school age children participate in 20 minutes of math play after school perhaps that will lead to great gains as well.
Below you will find photos of projects that I have done with my own tiny person at home as she has grown. Each picture links to a blog post about it! I will also feature ideas for how to get K-6 students to play as well. In addition, you will find my presentation (and free task cards) at the Regional NCTM 2015 conference: Math Play: 20 Minutes a Day.
