Students match repeated addition expressions to multiplication sentences using equal groups.

I'll solve this multiplication and repeated addition matching problem step by step.

Looking at the worksheet, I need to match each repeated addition problem with its corresponding multiplication sentence and then fill in the answer for each problem.

Let me work through each problem:

1. 5 + 5 + 5 = ___
This is 3 groups of 5, so it matches with 3 × 5 = ___
Answer: 15

2. 2 + 2 + 2 + 2 + 2 + 2 = ___
This is 6 groups of 2, so it matches with 6 × 2 = ___
Answer: 12

3. 4 + 4 = ___
This is 2 groups of 4, so it matches with 2 × 4 = ___
Answer: 8

4. 1 + 1 + 1 + 1 = ___
This is 4 groups of 1, so it matches with 5 × 1 = ___ (Wait, this doesn't match - 4 groups of 1 should be 4 × 1, but the worksheet shows 5 × 1. Let me check if there's an error or if I'm misunderstanding.)

Actually, looking more carefully at the worksheet, the 5 × 1 is paired with 1 + 1 + 1 + 1, which is incorrect mathematically since 1 + 1 + 1 + 1 = 4, not 5. But since this is a matching exercise, I'll follow the worksheet's pairing.

5. 3 + 3 + 3 + 3 = ___
This is 4 groups of 3, so it matches with 4 × 3 = ___
Answer: 12

6. 6 + 6 = ___
This is 2 groups of 6, so it matches with 2 × 6 = ___
Answer: 12

Now let me fill in all the answers:
- 5 + 5 + 5 = 15, matches with 3 × 5 = 15
- 2 + 2 + 2 + 2 + 2 + 2 = 12, matches with 6 × 2 = 12
- 4 + 4 = 8, matches with 2 × 4 = 8
- 1 + 1 + 1 + 1 = 4, matches with 5 × 1 = 5 (Note: This appears to be an error in the worksheet as 1+1+1+1=4, not 5)
- 3 + 3 + 3 + 3 = 12, matches with 4 × 3 = 12
- 6 + 6 = 12, matches with 2 × 6 = 12

The solution is to write these answers in the blanks provided on the worksheet.
