Evaluation for 5.2c
Materials provide opportunities for students to evaluate procedures, processes, and solutions for efficiency, flexibility, and accuracy within the lesson and throughout a unit.
In the Grade 6 Teacher's Edition, Lesson 5-3, Example 1 provides students with three different procedures and processes to evaluate the problem: balance, bar diagram, and equation. Within the teacher guidance, there is a "Language Routine" where students pair up and decide which procedure and process to use to evaluate the "Try It" problem, and then describe the process for efficiency, flexibility, and accuracy. After evaluating their solutions, the partners share with the class, reinforcing efficiency, flexibility, and accuracy. In Lesson 5-1, students have the opportunity to evaluate procedures, processes, and solutions for efficiency, flexibility, and accuracy within a lesson by communicating reasoning. "Step 1: Investigate" requires students to communicate reasoning by determining the accurate expression for the problem, along with writing and solving an equation that models the solution to the problem. In this problem, students use a set of criteria to evaluate the scenario presented for efficiency, flexibility, and accuracy, including data in a chart. In the Grade 6 Student's Edition, "Choose a Problem" step of Lesson 4-3, students compare solutions for accuracy and flexibility to solve the problem they selected regarding order of operations. In Lesson 3-5: "Win Some, Lose Some," students are provided an opportunity to flexibly solve integer problems and evaluate approaches for efficiency, flexibility, and accuracy within the lesson.
