Let’s solve each addition problem step by step using the number line.
---
First Problem: 3 + 3 + 2 = ?
We start at 0.
→ First jump of 3 lands us on 3.
→ Second jump of 3 from 3 lands us on 6.
→ Third jump of 2 from 6 lands us on 8.
So, 3 + 3 + 2 =
8
✔ Verified: 3+3=6, 6+2=8 → Correct.
---
Second Problem: 4 + 1 + 2 = ?
Start at 0.
→ Jump of 4 lands on 4.
→ Jump of 1 from 4 lands on 5.
→ Jump of 2 from 5 lands on 7.
So, 4 + 1 + 2 =
7
✔ Verified: 4+1=5, 5+2=7 → Correct.
---
Third Problem: 1 + 3 + 1 = ?
Start at 0.
→ Jump of 1 lands on 1.
→ Jump of 3 from 1 lands on 4.
→ Jump of 1 from 4 lands on 5.
So, 1 + 3 + 1 =
5
✔ Verified: 1+3=4, 4+1=5 → Correct.
---
Fourth Problem: 2 + 2 + 2 = ?
Start at 0.
→ Jump of 2 lands on 2.
→ Another jump of 2 from 2 lands on 4.
→ Final jump of 2 from 4 lands on 6.
So, 2 + 2 + 2 =
6
✔ Verified: 2+2=4, 4+2=6 → Correct.
