Abstract
Abstract An educational gaming apparatus consisting of a set of numbered blocks, at least six in number and dodecahedron in shape, and a single operator block, also of dodecahedron configuration, each of the number blocks bearing one of the digits zero to nine on each of its faces with an unbiased distribution of the digits zero to nine on the set of numbered blocks, the operator block bearing one or more of the basic mathematical symbols of addition, subtraction, multiplication or division or their equivalent on each of its faces such that at least one of the basic mathematical symbols or their equivalent is present on an uppermost face section of the operator block for any random toss by an individual who can then arrange the blocks in such an order that the uppermost faces of the blocks indicate a mathematical problem and its solution.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
An educational gaming apparatus including: a set of at least six number blocks each having the configuration of a regular hedron, each number block having at least twelve face sections bearing a numeral or its equivalent on each of said face sections with an unbiased distribution of said numerals on said set of number blocks; a single operator block having the same configuration as said number blocks and having at least twelve face sections each bearing one or more of the basic mathematical symbols of addition, subtraction, multiplication or division or their equivalent such that at least one of said basic mathematical symbols or their equivalent is present on any uppermost face section of said operator block for any random position thereof; said apparatus adapted for random toss of said number blocks and said operator block by one or more players and adapted for arrangement of said blocks after said toss in an order such that uppermost face sections of selected number blocks and said operator block indicate a mathematical problem and solution.
Claim 2
Dependent Claim
173 words
An educational gaming apparatus including: a set of at least six number blocks each having the configuration of a regular hedron, each number block having at least twelve face sections bearing a numeral or its equivalent on each of said face sections with an unbiased distribution of said numerals on said set of number blocks; a single operator block having the same configuration as said number blocks and having at least twelve face sections each bearing one or more of the basic mathematical symbols of addition, subtraction, multiplication or division or their equivalent such that at least one of said basic mathematical symbols or their equivalent is present on any uppermost face section of said operator block for any random position thereof; said apparatus adapted for random toss of said number blocks and said operator block by one or more players and adapted for arrangement of said blocks after said toss in an order such that uppermost face sections of selected number blocks and said operator block indicate a mathematical problem and solution.
Claim 3
Dependent Claim
21 words
An educational gaming apparatus as in claim 1 in which: said number blocks and said operator block are dodecahedron in configuration.
Claim 4
Dependent Claim
20 words
An educational gaming apparatus in claim 1 in which: said number blocks and said operator block are icosahedron in configuration.
Claim 5
Dependent Claim
27 words
An educational gaming apparatus as in claim 1 in which: all of the numerals zero through nine appear at least once on each of said number blocks.
Claim 6
Dependent Claim
18 words
An educational gaming apparatus as in claim 4 in which: none of said numerals appear more than twice.
Claim 7
Dependent Claim
33 words
An educational gaming apparatus as in claim 1 in which: at least one of said face sections of one of said number blocks bears a legend indicating choice of even or odd number.
Claim 8
Dependent Claim
28 words
An educational gaming apparatus as in claim 1 in which: at least one of said face sections of said operator block bears a legend indicating choice of operation.
Claim 9
Dependent Claim
25 words
An educational gaming apparatus as in claim 1 in which: at least one of said face sections of said operator block bears alternative mathematical symbols.
Claim 10
Dependent Claim
241 words
An educational gaming apparatus including: a set of six number blocks each block being dodecahedron in configuration, each number block having twelve face sections bearing a numeral or its equivalent thereon, one of said face sections of one of said number blocks bearing a legend indicating a choice of even numbers; another of said face sections of one of said number blocks bearing a legend indicating a choice of odd numbers, said set of number blocks designed such that each of the numerals zero to nine appears at least once on each block and appears seven times on said set thereby providing an unbiased distribution of said numerals on said set of number blocks; a single operator block dodecahedron in configuration having twelve face sections, some of said face sections bearing one or more basic mathematical symbols of addition, subtraction, multiplication or division thereon and at least one of said face sections bearing a legend indicating choice of symbols such that at least one of said basic mathematical symbols or choice thereof appears on an uppermost face section of said operator block for any random position of said operator block; said apparatus adapted for random toss of said number blocks and said operator block by one or more players and adapted for arrangement of said blocks after said toss in an order such that uppermost face sections of selected number blocks and said operator block indicate a mathematical problem and solution.
