This board is used to help children learn the combinations making teen numbers. Children have an easier time learning the double facts (6+6=12, etc.) than the odd number facts. The doubles serve to anchor the children. The neighbor combinations are one more than the double facts. 6+7 is one more than 6+6. Games associated with this board are described in Structural Arithmetic II: Teacher's Guide, see page 72, 73.

This item includes a two piece interlocking board plus thin number markers 10 to 20.
