ABSTRACT:
Apparatus for improving the skills of mathematical computation and alphabet usage, comprising a computation selector in combination with an answer verifier. The computation selector comprises a problem board member and a selector member mounted for relative rotation with respect to each other. Computational problems are carried on the problem board member with the correct answer to each problem represented by a code marking or letter code on the problem board. Selection of a specific problem is governed by chance, being the result of rotation of the selector member in relation to the problem board. The answer verifier comprises an answer board member and a visibly distinct identifier member mounted for indexing movement with respect to each other. Letter codes from the problem board are arranged on the answer board member in uniform association with the numerical value of the correct answer represented by them. The correct answer numerical value is visually apparent and identified by the identifier member when the identifier member is indexed to visually mark the letter code for the problem from the problem board. Letters earned during play are available for use in forming words.
