Instructions for Use

Manny's Rumba has your child use base ten blocks to represent given numbers.

Look in the green square for the number of blocks you need. Then click and drag the base ten blocks onto the yellow paper until you have the correct number. The number in the background of the paper tells you the number of blocks you have on top of it. For the next problem, you may need to add or take away blocks to represent the new number correctly. Once you have practised numbers up to 100, click “100” on the far left of the screen to model numbers up to 1000.
