Unit review questions
1. From the same start, strip A spans 6 equal boxes and B spans 8. Which is longer?
Need a hint?
  • Line up one end of both strips.
  • Do not compare endpoints when the starting places differ.
2. Tower A is 6 equal blocks high. Tower B is 5 blocks high. Both start on the same ground line. Which tower is taller?
Need a hint?
  • Use one ground line for both towers.
  • A higher position on the page is not the same as a taller object.
3. A pretend balance holds J on the left and K on the right. Right is lower. Which conclusion fits?
Need a hint?
  • Use the supplied lower-side rule.
  • Weight cannot be concluded from drawn size alone.
4. Sort this record by color: blue, red, blue, blue, blue, red, blue, blue. How many are in the blue category?
Need a hint?
  • Write a label above each category.
  • A sorting rule must stay the same while you make the groups.

Use the skills in a new task

Use paper strips 4, 7, and 5 equal squares long. Sort them from shortest to longest; then sort six drawings: red, blue, red, red, blue, blue.

Work on paper or in your own document. Explain the choices you made.

  • Draw or label the numbers or shape features the task gives you.
  • Say why each calculation or shape choice follows the ideas in this unit.
  • Check that your answer fits the story or drawing in the task.
Compare with a model response

Length order is 4, 5, 7 squares. Color categories contain three red and three blue drawings. Color does not determine strip length.

A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
