## Description

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.

FEATURES

• 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.

## Ratings and Reviews

### 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!
