Recent studies have pointed out that many schoolchildren do not master the skill of solving non-routine mathematical problems. In this article, a trial study designed to encourage seventh and eighth grade students to learn and use problem solving strategies is discussed. The strategies consist of six heuristic strategies known as Simplify the Problem, Guess and Check, Look for a Pattern, Make a Drawing, Make a Systematic List and Work Backward. Classroom activities consisted of a short whole-class introduction, group studies and a final whole-class discussion on the given problem. The teachers role was to encourage and guide the pupils towards engaging in the problem. It is observed that in these classes some of these strategies are effective in learning, others are not.
Key words: Problem solving, problem solving strategies, non-routine problems, mathematics teaching.
