    How to Solve It suggests the following steps when solving a mathematical problem: First, you have to understand the problem. [2] After understanding, make a plan. [3] Carry out the plan. [4] Look back on your work. [5] How could it be better? If this technique fails, Pólya advises: [6] "If you cannot solve the proposed problem, try to solve first some related problem. Could you imagine a more ...

    Tasks that involve construction, use, and interpretation of multiple representations can lend themselves to rubric assessment, [7] and other assessment types suitable for open-ended activities. For example, tapping into visualization for math problem solving manifests multiple representations. [1] These multiple representations arise when each student uses their knowledge base and experience ...
