Count up to three

Count each object once in sets of zero to three.

1. Move or point to each dot once; an empty set has zero objects.
2. Work through the example. Explain how its evidence supports the answer.
3. Try a new question; use the explanation to check your thinking.

Try it together

Write or draw your own example with different numbers. Solve it, then ask a partner to check the method as well as the answer.
