Est. Class Sessions: 1

Summarizing the Lesson

Play a game of Number Line Target with a student and ask him or her to explain his or her choices of numbers. Discuss strategies for moving on the number line. Use prompts similar to the following:

If a student chooses 20 when the sum is at 30, ask:

X
  • How can you move 20 on the number line without counting each one? (Possible response: I count two more tens, 40, 50.)

If a student chooses 30 when the marker is on 25, ask:

X
  • How can you move 30 on the number line without counting each one? (Possible response: I count by tens starting at 25. I know that they will all end in 5, so 35, 45, 55.)

Refer students to the vignette on the Number Line Target page in the Student Guide. After describing the game plays between Tanya and Jerome, ask student pairs to discuss Questions 1–3.
