Discussed are techniques of presentation and solution of the Classical Cake Problem. A frosted cake with a square base is to be cut into n pieces with the volume of cake and frosting the same for each piece. Needed are minimal geometric concepts and the formula for the volume of a prism. (JP)

The theme for the column is composing and solving problems. One section has teacher-developed problems for the primary grades. The other section contains student-authored problems for the upper grades, submitted for a student problem contest. (LS)

Illustrated is the mathematical analysis of a three-dimensional game using techniques from the calculus of finite differences. This game is an analog of the familiar two-dimensional game, Dots and Squares. (JP)

The role of division of whole numbers in problem solving and the implications for teaching division computation are examined. Deleting the teaching of division facts, and obtaining solutions by using multiplication facts, is advocated. (DT)

Presented are ten problems for the mathematics laboratory in the intermediate grades, the children's reactions to the laboratory, and the authors' evaluation of it. (RP)

Before judging a student's diagram correct or incorrect, the mental associations made by the student between his diagram and the problem should be known. This is a follow-up to the author's article in the November 1970, Arithmetic Teacher." (RS)

The computer is used to explore some worthwhile mathematics in the secondary school classroom. The problems discussed center around Gauss' Existence Theorem for constructible regular polygons. (FL)
