Active Share

  1. Ask groups to share their thinking strategy as they solved the problem in Play Part 2.
    1. Target an estimated time for students to share their strategy so there is enough time for every group to share and ask/answer questions as needed.
    2. Teacher Tip: Remind students to actively listen to each other as they are sharing their strategies. This is the time to ask questions and see if classmates solved the steps similar to you.
  2. Evaluate and address any common mistakes or misconceptions as students are explaining their thinking strategy.

Digital Documentation

  • Teachers can record themselves modeling how to use manipulatives to solve the same problem in Play Part 1 to reference.
  • Teachers can use video to record the process during Play Part 2 of the groups independently solving addition problems.

Student-Driven Visible Thinking

  • In Active Share, groups will be able to share their thinking strategy that they used in Play Part 2 to solve addition problems using their number line, 123 Robot and manipulatives (crayons).

Metacognition-Reflecting Together

  • Journal Prompts: What is another example of where you could use objects to help solve a problem?
  • Process Question: What is the relationship between a set of numbers and manipulatives?  
  • Collaborating Question: Did your group overcome any challenges today? Explain how your group worked together as a team to complete each step and solve the addition problem.
