Let’s solve each addition problem one by one. We’ll add the two numbers in each box and write the answer below the line.
---
a)
2 + 1 = 3
→ Think: Start at 2, count up 1 more → 3
b)
3 + 1 = 4
→ Start at 3, count up 1 → 4
c)
4 + 1 = 5
→ Start at 4, count up 1 → 5
d)
5 + 1 = 6
→ Start at 5, count up 1 → 6
e)
2 + 2 = 4
→ 2 plus another 2 is 4 (like having 2 apples and getting 2 more)
f)
3 + 3 = 6
→ 3 plus 3 is like doubling 3 → 6
g)
4 + 4 = 8
→ Double 4 → 8
h)
5 + 5 = 10
→ Double 5 → 10
i)
3 + 2 = 5
→ Start at 3, count up 2 → 4, then 5
