Instructions: A square array has the same number of rows and columns. The square root tells us how many rows (or columns) are in the array.
Part A: Draw Square Arrays
Draw dots or circles to complete each square array.
1. 3 × 3 = 9
Draw 3 rows of 3 dots:
2. 4 × 4 = 16
Draw 4 rows of 4 dots:
3. 5 × 5 = 25
Draw 5 rows of 5 dots:
Part B: Find the Square Root
Look at each array and write how many rows (or columns) there are.
4. Total dots = 4, so the square root of 4 = ______
5. Total dots = 36, so the square root of 36 = ______
Part C: Complete the Table
| Square Number | Array Size (rows × columns) | Square Root |
|---|---|---|
| 1 | 1 × 1 | ______ |
| 9 | ______ × ______ | ______ |
| 16 | ______ × ______ | ______ |
| 25 | ______ × ______ | ______ |
| 49 | ______ × ______ | ______ |
