ABSTRACT:
A multiplication facts learning aid kit comprises a model amenable to computerization, teachers manual, set flash cards, and student materials to enable the learner to know the multiplication facts without rote memory.
The model comprises a base and a plurality of square prismatic blocks with impressions of cubical units being proportionally-graduated squares up to the square of each numeral through twelve with the first cubic block being 1 cubed while the remaining plies represent integral multiples of the dimensions of said first block. Each composite multiple segmented ply represents multiplication facts in which multipliers are consistently the smaller numeral or are of the same value as the multiplicand. The width and height of the plies increase proportionally as the numeral affixed to the frontal surface corresponds to the value of that multiplication fact.
Plies may be positioned to identify pattern relationships between sets of multiplication facts. Lateral manipulation of the appropriate ply enables the user to see, feel, and count representative blocks for each multiplication fact through 12 squared.
