This practice guide from the What Works Clearinghouse in the US provides five recommendations for improving pupils’ mathematical problem solving in Grades 4 to 8 (the equivalent of Years 5 to 9). The guide is aimed at teachers and policymakers who want to improve the mathematical problem solving of pupils. Recommendations include:
- Assisting pupils in monitoring and reflecting on the problem-solving process.
- Teaching pupils how to use visual representations.
- Exposing pupils to multiple problem-solving strategies.
The guide presents evidence-based suggestions for putting each recommendation into practice and describes the problems that may be encountered, as well as possible solutions. Each recommendation is rated based on the strength of the research evidence that has shown the effectiveness of the recommendation. The recommendations listed above have strong to moderate evidence of effectiveness.
