This is a reference book of number facts and patterns. It is meant to be looked at and played with. It can be used in many different ways, such as: games of comparison, remembering multiplication facts, or to facilitate counting by different numbers. Originally it would be in a 3 ring binder with the blacked out numbers being holes in the pages slid into plastic sheets so you could see through the little windows that it makes.
