Unit review questions
1. Count the marks in this line: ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ●. How many marks are shown?
Need a hint?
  • Use a small circle to show a dot has been counted.
  • Do not count the same dot again just because it is near another dot.
2. Start at 60 and take 4 counting steps of 10. Where do you stop?
Need a hint?
  • Point to the starting numeral before moving.
  • The starting number is not a new step.
3. These marks are seen once around a ring, starting at the chosen first mark: ● ● ● ● ● ● ● ● ● ● ● ● ● ●. What is their total?
Need a hint?
  • A star beside the start prevents a second lap.
  • Stop before counting the first dot again.
4. A card asks for 19 dots. How many dots should your finished drawing contain?
Need a hint?
  • Count while making each mark.
  • A requested group is exact; do not add an extra mark after reaching the number.

The download contains your current choices and any checked feedback. Keep the separate transfer-task work in your own document; downloading its instructions does not mark it complete.

Use the skills in a new task

Draw 14 dots as two rows of seven. Circle each dot once while an adult counts; move the dots into a ring and explain the total.

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

Fourteen dots remain fourteen when their positions change. Two rows of seven contain fourteen; a ring changes where the dots are, not their number.

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