Math in Focus Virtual Manipulative CD-ROMs
If you don't like the clutter of all the math manipulatives or storage is an issue or you have a child who just works and learns better at the computer, consider using virtual manipulatives. These CD-ROMs include virtual manipulatives that are used with the Math in Focus series. Primary for K-2 includes virtual counters, base-ten blocks, number lines, number charts, graphs, fractions, geometry, measurement, algebra, and probability manipulatives. Intermediate for grades 3-5 includes counters, base-ten blocks, number lines, number charts, graphs, fractions, geometry, measurement, algebra, and probability manipulatives to correspond to those grades.
Although designed with the Math in Focus curriculum in mind, these would be fun, colorful, practice for any math program. These CD-ROMs are interactive whiteboard ready too.
