Addition Circles math worksheet for practicing addition of decimal numbers using two number wheels.

Let’s solve this step by step.

We have two wheels with numbers. We need to pick one number from the left wheel and one from the right wheel, add them together, and do this six times with different pairs.

Left Wheel Numbers:
- 1,855
- 4,640
- 2,019
- 3,209
- 1,098
- 3,577
- 4,879
- 3,891

Right Wheel Numbers:
- 3,592
- 2,186
- 4,321
- 888
- 447
- 2,909
- 1,234
- 794

We’ll pick 6 different pairs (one from each wheel) and add them. Let’s choose easy ones first to avoid mistakes.

Pair a:
Pick 1,855 (left) + 794 (right)
→ 1,855 + 794 = ?

Let’s calculate:
1,855
+ 794
= 2,649 ✔

Pair b:
Pick 4,640 (left) + 888 (right)
→ 4,640 + 888 = ?

4,640
+ 888
= 5,528 ✔

Pair c:
Pick 2,019 (left) + 447 (right)
→ 2,019 + 447 = ?

2,019
+ 447
= 2,466 ✔

Pair d:
Pick 3,209 (left) + 1,234 (right)
→ 3,209 + 1,234 = ?

3,209
+1,234
= 4,443 ✔

Pair e:
Pick 1,098 (left) + 2,909 (right)
→ 1,098 + 2,909 = ?

1,098
+2,909
= 4,007 ✔

Pair f:
Pick 3,577 (left) + 3,592 (right)
→ 3,577 + 3,592 = ?

3,577
+3,592
= 7,169 ✔

All calculations checked. These are six different pairs — no repeats used.

Final Answer:
a. 2,649
b. 5,528
c. 2,466
d. 4,443
e. 4,007
f. 7,169
