Proof Lab by Math Empowered

Math Empowered

About this app

Proof Lab brings Math Empowered's virtual manipulatives to your phone and tablet, so you can model a math idea, build it piece by piece and prove why it works.

What you can do:
• Build with algebra tiles, base-ten blocks, counters, cubes, arrays, money and more.
• Work across several boards and switch between them with one tap.
• Draw on the board, cross pieces off to show subtraction, and reverse a piece's sign.
• See the live value of what you've built update as you work.
• Pinch to zoom, then fit every piece back into view.
• Save a board, or export it as an image to share with your class.
• Keep working offline: your boards are saved on your device.

Proof Lab is part of the Math Empowered Suite. Sign in with the same account you use on the web; the app does not sell or create accounts.

Built for teachers, students and families who want math to make sense.
