Let’s solve the problems step by step.

Top Worksheet: “Make a 10 — Solve the equations.”

We need to fill in the blanks so that each equation equals 10.

Column 1:
- 8 + __ = 10 → 10 - 8 = 2
- __ + 4 = 10 → 10 - 4 = 6
- 7 + __ = 10 → 10 - 7 = 3
- 9 + __ = 10 → 10 - 9 = 1
- __ + 5 = 10 → 10 - 5 = 5
- 2 + __ = 10 → 10 - 2 = 8
- __ + 6 = 10 → 10 - 6 = 4

Column 2:
- __ + __ = 10 → Many answers possible, e.g., 5 + 5 = 10 (or any pair that adds to 10)
- 8 + 2 = __ → 8 + 2 = 10
- 1 + __ = 10 → 10 - 1 = 9
- __ + 3 = 10 → 10 - 3 = 7
- 5 + __ = 10 → 10 - 5 = 5

Column 3:
- 0 + __ = 10 → 10 - 0 = 10
- 7 + 3 = __ → 7 + 3 = 10
- 10 + __ = 10 → 10 - 10 = 0
- __ + 2 = 10 → 10 - 2 = 8
- __ + 9 = 10 → 10 - 9 = 1

Bottom Worksheet: “Make a 10 — Circle two numbers that make ten. Then solve.”

We look for two numbers in each row that add up to 10, then add the third number.

Row 1:
- 7 + 4 + 3 → 7 + 3 = 10 → 10 + 4 = 14
- 2 + 5 + 8 → 2 + 8 = 10 → 10 + 5 = 15
- 5 + 5 + 5 → 5 + 5 = 10 → 10 + 5 = 15

Row 2:
- 6 + 2 + 4 → 6 + 4 = 10 → 10 + 2 = 12
- 5 + 2 + 5 → 5 + 5 = 10 → 10 + 2 = 12
- 1 + 9 + 8 → 1 + 9 = 10 → 10 + 8 = 18

Row 3:
- 3 + 5 + 5 → 5 + 5 = 10 → 10 + 3 = 13
- 8 + 2 + 6 → 8 + 2 = 10 → 10 + 6 = 16
- 6 + 7 + 3 → 7 + 3 = 10 → 10 + 6 = 16

Row 4:
- 1 + 1 + 4 → Wait — no two numbers make 10 here? Let’s check: 1+1=2, 1+4=5, 1+4=5 → Hmm, maybe it’s a typo? But if we must, perhaps they meant 1 + 9 + 4? But as written: 1 + 1 + 4 = 6 → but instruction says “circle two that make ten” — none do. Maybe it’s 1 + 9 + 4? Let’s assume it’s 1 + 9 + 4 → 1+9=10 → 10+4=14. But original says “1 + 1 + 4”. That doesn’t work. Perhaps it’s “1 + 9 + 4”? I’ll go with what’s written: 1 + 1 + 4 = 6 — but that breaks the rule. Alternatively, maybe it’s “1 + 4 + 5”? Not sure. Let’s skip and come back.

Wait — looking again: maybe it’s “1 + 9 + 4”? Because 1+9=10. But image says “1 + 1 + 4”. That must be an error. For learning purposes, let’s assume it’s “1 + 9 + 4” → 10 + 4 = 14

Next:
- 3 + 3 + 7 → 3 + 7 = 10 → 10 + 3 = 13
- 2 + 2 + 8 → 2 + 8 = 10 → 10 + 2 = 12

Row 5:
- 6 + 7 = __ → Wait, only two numbers? But instruction says “circle two that make ten” — 6+7=13, no pair makes 10. Maybe it’s “6 + 4 + 7”? But written as “6 + 7 = ___”. Probably missing one number. If we assume it’s “6 + 4 + 7”, then 6+4=10 → 10+7=17. But as written, it’s incomplete. Let’s assume typo and use “6 + 4 + 7” → 17

Next:
- 4 + 7 + 6 → 4 + 6 = 10 → 10 + 7 = 17
- 1 + 3 + 7 → 3 + 7 = 10 → 10 + 1 = 11

But wait — last row has “4 + 7 + 6” and “1 + 3 + 7” — those are fine.

Actually, looking again at bottom worksheet:

The last row of the bottom sheet:
Left column: “6 + 7 = ___” — this seems like a mistake because there’s no third number. But above it says “___ + ___ = ___” — maybe it’s meant to be “6 + 4 + 7”? I’ll assume that for consistency.

Similarly, the fourth row left: “1 + 1 + 4” — probably should be “1 + 9 + 4”.

To stay true to the task, I’ll solve as written where possible, and note inconsistencies.

But since this is for a student, let’s correct obvious typos to match the “make a 10” strategy.

So revised:

Row 4 left: Assume “1 + 9 + 4” → 1+9=10 → 10+4=14

Row 5 left: Assume “6 + 4 + 7” → 6+4=10 → 10+7=17

Now all make sense.

Final answers for bottom worksheet:

Row 1: 14, 15, 15
Row 2: 12, 12, 18
Row 3: 13, 16, 16
Row 4: 14, 13, 12
Row 5: 17, 17, 11
