Instructions

Move the blocks around using your mouse.

You can select a block by clicking on it.

You can select many blocks by drawing a rectangle on the screen surrounding them.

Once blocks are selected you can:

  • Join them (when joined they automatically cut themselves into 10s), or
  • Break them into "1" blocks
  • Delete them

You can Add new blocks of size 1 to 10 using the Add button.

Uses

Demonstrate addition facts (example: 4+1=5), subtraction (example 5-1=4), multiplication (example 4 2s make 8), division (6 can be broken into 3 2s, or 2 3s) ... and more!

Make nice patterns: pyramids, squares, rectangles ... even shapes like cats.
