Unit review questions
1. Figure E is closed and flat with 3 straight sides. What category fits?
Need a hint?
  • Count all sides along one complete trip around the boundary.
  • Equal side lengths are not required for the broad polygon names.
2. A rectangle has 3 rows with 6 equal squares in each row. How many squares cover it?
Need a hint?
  • Draw all rows with the same number of columns.
  • Count tiles, not grid intersections or the outside outline.
3. A drawn card is partitioned into three equal-area shares. What fraction of the whole is one share?
Need a hint?
  • Confirm equal areas before naming the shares thirds.
  • Three pieces are not automatically three equal shares.
4. A whole has 24 equal tiles. Two pieces cover 12 tiles each without overlap. Are the pieces equal shares even if their outlines differ?
Need a hint?
  • Use equal tile counts to compare covered area.
  • Different outlines do not automatically mean different amounts of a whole.

Use the skills in a new task

Draw a rectangle as three rows of four equal squares, then divide it into three equal rows.

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

There are twelve tiles. Each row has four tiles and covers one third of the rectangle because the three rows have equal area. The thirds rebuild the whole.

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