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.
The materials provide opportunities for students to evaluate mathematical representations, models, strategies, and solutions for efficiency throughout learning pathways. In "Use Area Models to Represent the Distributive Property," students compare two strategies—counting square units and using the area formula—to determine which method is more streamlined. In "Add Within 1,000 Using Algorithms," students are prompted with, "Did we need to regroup tens or ones in our work?", and compare the vertical algorithm with expanded form to evaluate which strategy is more efficient in different scenarios.The materials provide opportunities for students to evaluate mathematical representations, models, strategies, and solutions for flexibility throughout learning pathways. In "Subtract Within 1,000 Using Algorithms," students learn and apply multiple strategies—baseten models, expanded form, and standard algorithm—and are prompted to compare and contrast these methods. Teacher-guided questions, such as "How are these two algorithms similar? How are they different?" support students in recognizing when and why to apply different strategies.The materials provide opportunities for students to evaluate mathematical representations, models, strategies, and solutions for accuracy throughout learning pathways. In "Compare Fractions with Same Numerator or Denominator," students use verbal descriptions, visual pie models, and fraction tiles to reinforce accurate reasoning. In "Add & Subtract 3-Digit Numbers to Solve Word Problems," students check solutions using a strip diagram, equation, and standard algorithm, promoting accurate verification through multiple representations. Additionally, prompts, such as"Is your answer reasonable? How do you know?" help students evaluate the correctness of their procedures and results.
