Free Math Apps
Free Math Apps
These apps are based on the visual models featured in Bridges in Mathematics. All apps are available in two or more versions: a web app for all modern browsers, and downloadable versions for specific operating systems and devices (such as Apple iOS for iPad).
New! Share Work with Others
Sharing in an app allows educators to pose problems and investigations for students using an 8-character code or link. Students can share their thinking with their teachers and classmates. Share codes remain available for continued use for 18 months from the date they are last accessed.
The sharing feature is available in Number Pieces, Number Rack, Number Line, Number Frames, Math Clock, Geoboard, and the Whiteboard App — and is coming to more apps soon.
Watch the video to learn how sharing works.

Partial Product Finder
Newly updated with support for arrays up to 50 x 50
Partial Product Finder allows multiplication combinations to be represented as a rectangle, or array, with dimensions that match the combination. This helps students develop the flexibility and conceptual understanding required to build fluency with basic facts and strategies for multiplication of larger numbers.
