Help students visualize and understand place value as they build numbers from 1?9,999,999. Set of 70 color-coded rods teaches numeric, written and expanded forms and includes 10 rods of each value: ones, tens, hundreds, thousands, ten thousands, hundred thousands, and millions. Both written and numeric forms of place value appear on each rod, and each rod's size also indicates the place value it represents. Rods snap together rods horizontally or vertically for maximum versatility. Includes Activity Guide and 9" x 12" double-sided, write-on/wipe-off Activity Card.
