www.elementOry.com Regrouping can be a difficult concept to conceptualize. I use ants to show that 10 ants (the ones column) can regroup under 1 ant hill in the tens column. Likewise, 10 ant hills can be regrouped under 1 mound in the hundreds column. Children can visually see the logic of regrouping and place value. The board and 100 tokens are available at ElementOry.com for only $10.
