Place Value Models Tool. This tool employs three types of models to help students understand numeric values from 0.001 to 1,000,000. The Base Ten Blocks, Base Ten Frames, and Place Value Disks present a hierarchy from most concrete (blocks) to most abstract (disks). The tool also presents opportunities to write numbers in standard notation and expanded notation.
