Apps that Encourage Number Sense

The days of timed testing are done! We encourage deep thinking and flexible number sense over speedy fact recall. Being able to apply math concepts flexibly is more important in today's workplace than fact recall. If you would like to give your child more experience with number sense, we recommend the following apps, available on PC, IOS, and Android devices.

Dragonbox Numbers

• Great for students learning to add and subtract single-digit numbers. The app forces students to visualize the operations.

Dragonbox Big Numbers

• Students visualize the standard algorithm using an engaging resource trading interface.

Dragonbox Elements

• Engaging Geometry app. Students learn about different shapes and how to prove similarity between them.

Dragonbox Algebra 5+

• Entrance to thinking algebraically for young children. You will have a difficult time seeing the algebra until students move into the later levels. It's a very clever approach for thinking about equivalence as well.

Dragonbox Algebra 12+

• See Algebra 5+, except more challenging and it goes even deeper into algebraic concepts.

Polyup

• Polyup is a math education app available freely on the web. With the goal of instilling creative problem solving and computational thinking skills into K-12 students, Polyup allows students to play with numbers and functions in a freeform environment.
