Virtual Manipulatives! app

Kids can use this iPad app to help them visualize concepts in fractions, decimals and percentages by making comparisons using virtual manipulatives.  There are pullout trays for fractions, decimals, and percentages.  Use the “i” settings to change to tiles or circles, snap to grid, and hide or show numbers.  There is also a pencil tool so students can write problems, equations and solutions in the space as they manipulate the tiles or circles.

There are no third-party ads with this free app, no data collection tools, or in-app purchases.
