Evaluation for 5.2c
Materials provide opportunities for students to evaluate mathematical representations, models, strategies, and solutions for efficiency, flexibility, and accuracy throughout learning pathways.
Thegrade 5 materials engage students in evaluating the accuracy of solutions. In Unit 1, students identify and explain which person solved for the product correctly, and thencontinue to identify the mistake.The lessons in thegrade 5 materials allow students to evaluate mathematical representations, models, strategies, and solutions for flexibility through learning pathways. In the Unit 1 whole group discussion, students are asked, "Did anyone solve a problem differently but still get the same answer? What did you do differently?" This allows student flexibility to evaluate their preferred strategy in comparison to another strategy.The materials provide opportunities for students to evaluate mathematical representations, models, strategies, and solutions for efficiency. For example, in Unit 2, the Guided Practice says, "Karla says solving for 100 – 42 – 16 is the same as solving for 100 – 42 + 16 because her teacher taught her that 42 and 16 should be added first, then subtracted from 100. Explain why she is not following the order of operations."
