Abstract
Abstract A counting cube for teaching pre-schoolers how to recognize and count numbers. The cube is hollow and is provided with six faces, the bottom face serving as a base and the top and side faces having openings therein lying within sockets each having the shape of a respective numeral in a sequential set thereof. Also, provided are five pieces each having the shape of one of the numbers in the set and dimensioned to be received in a correspondingly-shaped socket. Projecting from the rear of each piece is a hollow stem which is insertable into the cube through the related opening, the stems all having the same length and extending along axes which intersect at a common point. Transverse holes are formed in the first four stems in the sequence to define cross-through passages for the intersecting stems whereby only when the pieces are socketed in direct sequence is it possible to mount all pieces on the cube.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
A device for teaching preschool children to recognize and count numbers, said device comprising: A. a hollow cube having six like faces, the bottom face serving as a base, the top and side faces having openings therein lying within sockets having the shapes of a sequence of five numbers; B. a set of five pieces having the shape of said five numbers and dimensioned to be received in the correspondingly-shaped sockets; and C. hollow stems projecting from the rear of said pieces and insertable in said openings, said stems extending in the cube along axes which intersect at a common point, the stems on the pieces other than the piece representing the last number in the sequence having transverse holes therein which are so placed that the second stem in the sequence crosses through the passage formed by the hole in the first stem, the third stem crosses through the passage formed by the hole in the second stem and the fourth stem crosses through the passage formed by the hole in the third stem.
Claim 2
Independent Claim
175 words
A device for teaching preschool children to recognize and count numbers, said device comprising: A. a hollow cube having six like faces, the bottom face serving as a base, the top and side faces having openings therein lying within sockets having the shapes of a sequence of five numbers; B. a set of five pieces having the shape of said five numbers and dimensioned to be received in the correspondingly-shaped sockets; and C. hollow stems projecting from the rear of said pieces and insertable in said openings, said stems extending in the cube along axes which intersect at a common point, the stems on the pieces other than the piece representing the last number in the sequence having transverse holes therein which are so placed that the second stem in the sequence crosses through the passage formed by the hole in the first stem, the third stem crosses through the passage formed by the hole in the second stem and the fourth stem crosses through the passage formed by the hole in the third stem.
Claim 3
