This new math resource set introduces the concept of “carrying one” when doing two-digit addition. This is an important mathematic concept to learn in order to make working with large numbers manageable. The visual aspect of physically moving the 1 aids the child in understanding how to add larger numbers.
Set includes 6 base boards and 10 sets of numbers 0-9. Baseboards made from rubber backed polyester and numbers are 100% polyester.
