Count a set up to twenty

Count organized rows without counting an object twice.

1. Count one row, then keep counting from that total.
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.
