Unit review questions
1. 7 bags hold 4 beads each. How many beads are there altogether?
Need a hint?
  • Label group count and objects per group separately.
  • A multiplication model needs equal-sized groups.
2. Share 28 cards equally among 4 people. How many cards does each person receive?
Need a hint?
  • Draw the known number of share boxes first.
  • Report objects per person, not the number of people already given.
3. 42 cards are packed in groups of 6. How many complete packets are made?
Need a hint?
  • Write the packet size inside each group-circle.
  • Do not report the supplied group size as the missing group count.
4. Find the missing factor in 7×□=49.
Need a hint?
  • Use the known multiplication–division fact family.
  • A missing factor is not found by subtracting the known factor.

Use the skills in a new task

Use 24 counters to model four equal shares and groups of four. Explain why the answers count different things.

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

Four equal shares contain six counters each: 24÷4=6. Groups of four make six groups, also 24÷4=6. In one model six counts counters per share; in the other it counts groups.

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