Teaches place value; addition and subtraction of 2 digit numbers; regrouping; multiplication of 10, 9, 8, and 5.  It is often difficult to demonstrate to students the idea of regrouping. The structure of the Dual Board demonstrates easily that ten ones creates another ten – you physically run out of space for ones – and forces children to regroup them (or exchange them) for a ten-block.

The Dual Board is sold without blocks although its use requires ten 10-blocks and twenty 1-blocks.
