A program written in PASCAL designed to find the number of binary trees possible for a given number of nodes is presented. The problem was found to be highly motivating and exciting for the group of introductory computer science students with whom it was used. (MP)

This article considers the sum of a finite geometric series as applied to numeric data storage in the memory of an electronic digital computer. The presentation is viewed as relevant to programing in several languages and removes some of the mystique associated with syntax constraints that any language imposes. (MP)

An elective unit was developed for a course (Math 20) which would teach students to program solutions to typical exercises. Development of the unit took place in a large senior high school in Alberta. The elective is 15 hours long, with the first five hours devoted to learning programming fundamentals and the final ten hours to programming…
