WALT: We Are Learning To divide one- and two-digit whole numbers by 10 and identify the tenths digit.

Success criteria: I can divide by 10, place digits in the ones and tenths columns, and explain what the tenths digit means.

Say it aloud: “Dividing by ten makes ten equal groups. The tenths digit tells how many tenths.”

1. 1 ÷ 10 = 0.1

Place value: ONES (blue) | TENTHS (green)

2. 2 ÷ 10 = 0.2

Place value: ONES (blue) | TENTHS (green)

3. 10 ÷ 10 = 1

Place value: ONES (blue) | TENTHS (green)

4. 24 ÷ 10 = 2.4

Place value: ONES (blue) | TENTHS (green)

5. Solve: 16 ÷ 10 = ________

Draw a place-value model or a 10-by-10 grid. Label the ones and tenths.

6. Solve: 30 ÷ 10 = ________

Show your thinking with a model.

7. Circle the tenths digit in 2.4.

8. Write the tenths digit in 1.6: ________

9. Explain why 24 ÷ 10 = 2.4. Use the words ones, tenths and share equally.

10. Challenge: Explain 37 ÷ 10 in two ways: using a place-value chart and using a grid or sharing model.

Spoken rehearsal notes: My partner said ________________________________

Helpful support: use counters, a place-value chart, or say your explanation before writing it.

Extension: Create a similar divide-by-ten example for a partner. Check their model and explanation.
