Abstract
Abstract A multiplication-division game containing chips (16) representing multiplication products and playing cards (14) representing multiplier-multiplicand combinations which equal the products of said chips. Each player has a placemat (10) for holding dealt and drawn cards. The chips are arranged in three piles (16) and the players take turns trying to capture the chips by combining pairs of cards whose products equal those of any one of the three top chips. The player who captures the most chips is declared winner; successful multiplier-multiplication cards being discarded. The players alternate play; with each turn a player draws a new card from a stack and matches pairs of cards against the chips until such player can no longer capture any more chips.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
A multiplication/division tutorial game comprising: (a) a plurality of product pieces, each bearing at least one occurrence of multiplication product number such that each product piece represents a different multiplication product, and such that said plurality of product pieces represent a set of multiplication products (b) a plurality of multiplier-multiplicand pieces, each bearing at least one occurrence of a whole multiplier-multiplicand number such that each multiplier-multiplicand piece represents only a single multiplier or multiplicand, said multiplier-multiplicand pieces comprising all possible multiplier-multiplicand number combinations of a given set of whole numbers which can be multiplied to equal the set of product numbers represented by said plurality of product pieces.
Claim 2
Dependent Claim
108 words
A multiplication/division tutorial game comprising: (a) a plurality of product pieces, each bearing at least one occurrence of multiplication product number such that each product piece represents a different multiplication product, and such that said plurality of product pieces represent a set of multiplication products (b) a plurality of multiplier-multiplicand pieces, each bearing at least one occurrence of a whole multiplier-multiplicand number such that each multiplier-multiplicand piece represents only a single multiplier or multiplicand, said multiplier-multiplicand pieces comprising all possible multiplier-multiplicand number combinations of a given set of whole numbers which can be multiplied to equal the set of product numbers represented by said plurality of product pieces.
Claim 3
Dependent Claim
23 words
The game apparatus of claim 1 wherein said product pieces comprise the products of multiplier 2 and multiplicands from 2 to 9 inclusive.
Claim 4
Dependent Claim
28 words
The game apparatus of claim 1 further including a plurality of placemats, each placemat having a plurality of spaces for the respective numbers of said set of numbers.
Claim 5
Dependent Claim
37 words
The game apparatus of claim 1 wherein said product pieces are chips with a product number on one side thereof and at least one multiplier-multiplicand combination of numbers for said product number on the reverse side thereof.
Claim 6
Dependent Claim
27 words
The game apparatus of claim 1 wherein said multiplier-multiplicand pieces are cards, each card having only a single multiplier or multiplicand number on one side thereof only.
Claim 7
Dependent Claim
54 words
The game apparatus of claim 1 wherein said product pieces are chips with a product number on one side thereof and at least one multiplier-multiplicand combination of numbers for said product number on the reverse side thereof, and said multiplier-multiplicand pieces are cards, each card having a multiplier-multiplicand number on one side thereof only.
Claim 8
Dependent Claim
58 words
The game apparatus of claim 1 wherein said product pieces represent all the multiplication product numbers of all possible multiplier-multiplicand combinations of numbers from two to nine and said multiplier-multiplicand pieces comprise all the possible multiplier and multiplicand numbers only a single multiplier or multiplicand from two to nine which equal the respective product numbers of said chips.
Claim 9
Dependent Claim
88 words
The game apparatus of claim 1 wherein said product pieces are composed of a plurality of groups, each group being identified by a respective indicium, the indicia for respective groups being different, the pieces of one group representing all the product numbers of a given multiplier number and a series of sequential multiplicand numbers within a given range, the pieces of another group representing all the product numbers of a multiplier higher than said given multiplier number in a series of sequential multiplicand numbers within a given group.
Claim 10
Dependent Claim
21 words
The game apparatus of claim 8 wherein said indicia are colors, the product pieces of each group having a different color.
Claim 11
Dependent Claim
47 words
The game apparatus of claim 9 wherein for each group of product pieces there are provided a group of multiplier-multiplicand pieces for the combinations of multiplier-multiplicand numbers which yield the product numbers of said group, each multiplier-multiplicand piece bearing the same indicium as its corresponding product pieces.
