This interactive/virtual manipulative provides base ten blocks that consist of individual "cubes," "rods," "flats," and "thousands-cube" (ten of each set for base 10). The activity reinforces students' knowledge of thousands, hundreds, tens, and ones. Students can either enter a number and see the visual representation, or they can create a number by selecting the appropriate base ten blocks. As students add or remove base 10 blocks, they can see the numbers increase or decrease to determine if they are on the right track.
