Strand: Mathematical Practice Standards #1
Make sense of problems and persevere in solving them. Explain the meaning of a problem, look for entry points to begin work on the problem, and plan and choose a solution pathway. When a solution pathway does not make sense, look for another pathway that does. Upon finding a solution, look back at the problem to determine if the solution is reasonable and accurate, often checking answers to problems using a different method or approach. Second grade students persevere as they solve two-step problems, in which they need to make sense of a variety of problem types. Listen and look for students that exhibit the following behaviors: • give a good explanation of the problem • think about a plan before jumping into the solution • think of similar problems, try special cases, or use a simpler form of the problem • if needed, organize data or use representations to help make sense of the problem • identify likely strategies for solving the problem • pause when solving problems to make sure that the work being done makes sense • make sure the answer makes sense before stopping work
