Fourth graders take on nine mixed-number computations with like denominators — 2 1/4 + 1 2/4, 5 6/8 - 2 3/8, 1 3/7 + 3 2/7, 6 7/10 - 4 3/10, and 4 5/6 - 1 3/6 among them — adding the whole numbers and the fraction parts separately. The answers stay tidy because no regrouping is needed.
Part B is a four-pair matching round connecting expressions like 2 3/8 + 1 4/8, 5 4/5 - 3 1/5, 3 1/6 + 2 3/6, and 4 5/7 - 2 2/7 to their mixed-number results. Pairing computation with matching cements how mixed numbers behave when you add and subtract.

Part A: Fill in the Blank
Write the missing word or number on each line.
1. 214 + 124 = 334.
2. 568 − 238 = 338.
3. 137 + 327 = 457.
4. 6710 − 4310 = 2410.
5. 325 + 225 = 545.
6. 456 − 136 = 326.
7. 249 + 339 = 579.
8. 7312 − 5112 = 2212.
9. 113 + 213 = 323.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
238 + 148
→ 378
235
545 − 315
→ 235
237
316 + 236
→ 546
