Number Pieces Basic helps students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students can use the number pieces to represent multi-digit numbers, count, regroup, add, and subtract. The drawing tools allow students to label representations and show their understanding.

Note: Number Pieces, an advanced version of Number Pieces Basic, is also available in the App Store. Number Pieces has additional features for representing larger numbers and multiplication and division concepts.


• Add and manipulate pieces (ones, tens, and hundreds).

• Join pieces in groups of ten or break them apart (e.g., 10 ones into 1 ten and vice versa).

• Choose from three different colors to clearly identify groups or pieces.

• Move, rotate, and duplicate pieces individually or as a group.

• Use the drawing tools to label representations and show understanding.

• Write equations and expressions with the text tool.

Could be better

I like the idea of this app and some of the features. However, I wish the pieces were smaller when you bring them out onto the whiteboard. When you make the screen smaller it seems like it will work but you are limited to a small space still and can't put pieces on over half of the board. I do love being able to change between 100s, 10s, and 1s. That's a great feature for regrouping in second grade.

Has potential but needs work

This app has good tools that give you the awesome ability to break up a ten or hundred block to show regrouping. I can see the potential to use it to model this process for my students. Even better, they could use it independently or in pairs to work through problems.

However, I got stuck repeatedly when it came to alternating between drawing and blocks. For example, when I wanted to write 433-148 and then switch to the blocks I had to click on the calculator function to switch modes. Otherwise when I tried to click on the blocks, I would end up drawing on them.

Also, I wanted an "undo" button. If I accidentally clicked on a blocks pic to break it up, it would make a duplicate and I would have to delete it instead of pressing undo.

Thank you for giving us a free app to make the complicated base 10 process easier to understand for kids, but please make it more intuitive and user friendly!
