Let’s solve each problem step by step. The goal is to “find 10s” — that means break each number into two parts: one part is 10, and the other part is what’s left.
We’ll go box by box.
---
Top Left: 12 = 10 + □
We know 10 + ? = 12
So, 12 - 10 = 2 → Answer:
2
(Already filled in as example: 10 + 2)
---
Top Right: 16 = □ + □
Break 16 into 10 and the rest:
16 - 10 = 6 → So,
10 + 6
Check: 10 + 6 = 16 ✔️
---
Middle Left: 19 = □ + □
19 - 10 = 9 → So,
10 + 9
Check: 10 + 9 = 19 ✔️
---
Middle Right: 17 = □ + □
17 - 10 = 7 → So,
10 + 7
Check: 10 + 7 = 17 ✔️
---
Bottom Left: 11 = □ + □
11 - 10 = 1 → So,
10 + 1
Check: 10 + 1 = 11 ✔️
---
Bottom Right: 20 = □ + □
20 - 10 = 10 → So,
10 + 10
Check: 10 + 10 = 20 ✔️
---
All answers are verified.
Final Answer:
16 = 10 + 6
19 = 10 + 9
17 = 10 + 7
11 = 10 + 1
20 = 10 + 10
