Question
**3. a.** Write an array problem for 21 ÷ 3. Draw a simple picture that a child could use to determine the answer to the problem. **b.** Write an area problem for 21 ÷ 3. Draw a simple picture that a child could use to determine the answer to the problem. *Explanation for Diagrams:* - **Array Problem:** To visually represent 21 ÷ 3, you could draw an array consisting of three rows with seven dots in each row. This setup helps children see how many times three fits into twenty-one, illustrating division as repeated subtraction. - **Area Problem:** For the area model, consider making a rectangle with a total area of 21 and a width of 3. The length will then be 7, showing the division process spatially. This visual can help children understand how area relates to division.
