Games & Puzzles


Formative teaching is quickly identifying what every student knows AND intervening so they can learn more. It's essential to learning and yet extremely difficult to do. That's why we created Formative. We give teachers the tools they need to tap into student thinking (beyond multiple choice) and intervene before it's too late.

Math Playground

“Hi, my name is Colleen King. I created Math Playground in 2002 for students in my classes who needed a fun way to practice math facts. Since then, Math Playground has grown to include a wide variety of math topics, from problem solving and mathematical art to real world math and thinking games. When I'm not developing new activities for Math Playground, I teach at a mathematics learning center. I enjoy sharing math strategies with other educators and have presented my work at conferences such as NCTM and ISTE.”

Xtra Math

XtraMath is a Seattle 501(c)(3) nonprofit organization dedicated to math achievement for all. Our goal is to develop effective, efficient, adaptive, and intrinsically rewarding supplemental math activities.

XtraMath started in the fall of 2007 when David Jeschke, a computer programmer, volunteered at a local elementary school and recognized the need for an individualized math practice program. XtraMath spread rapidly to other classrooms by word of mouth and the program continues to evolve to meet the needs of the students, teachers, and parents.
