ABSTRACT:
A mathematics education apparatus comprises a base array. The base array includes a plurality of rows, with each row having ten receiving positions. The mathematics education device further comprises a plurality of number pieces that each correspond to a number, including at least one number piece corresponding to numbers one through ten. Each number piece has a linear length that is proportional to the number corresponding to that number piece. Additionally, each number piece is configured to cover a quantity of receiving positions on the base array equal to the number corresponding to that number piece.
