Unit review questions
1. A long flat figure has four square corners and opposite sides equal. Its adjacent sides are unequal. What is it?
Need a hint?
  • Trace and count the boundary edges.
  • Turning a triangle does not turn it into another shape.
2. Classify the mathematical shape rectangle.
Need a hint?
  • A solid has depth in its mathematical model.
  • A flat drawing of a solid is only a representation.
3. A model has six square faces, all the same size. What is it?
Need a hint?
  • Count the flat bases or faces stated in the description.
  • One circular view does not tell you whether a solid is a cone, cylinder, or sphere.
4. Two pieces leave uncovered space inside the target outline. What is the problem?
Need a hint?
  • Trace the target outline before joining pieces.
  • A correct flat composition has no inside gaps or overlaps.

Use the skills in a new task

Draw a square and split it corner to opposite corner. Name the two pieces and explain what happens when they meet again.

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

The diagonal splits the square into two triangles. Joining their matching diagonal sides rebuilds the square without a gap or overlap.

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