This Grade 4 sheet focuses on using rounding to estimate sums and differences. Grade 4 learners round addends to the nearest 10, 100, or 1,000, then add or subtract to find a reasonable approximation. Matching items pair real estimation problems with their rounded answers, while fill-ins reinforce the link between place value and estimation accuracy. Aligned to CCSS 4.NBT.3. Grade 4 students estimate sums.

Estimation and Rounding
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Grade 4 estimate: 89 + 14 to the nearest 10 is about 100.
2. Grade 4 estimate: 248 + 351 to the nearest 100 is about 600.
3. Grade 4 estimate: 612 - 289 to the nearest 100 is about 300.
4. Grade 4: 8,742 rounded to the nearest 1,000 is 9000.
5. Grade 4 estimate: 4,213 + 2,876 to nearest 1,000 is about 7000.
6. Grade 4: 3,500 rounded to the nearest 1,000 is 4000.
7. Grade 4 estimate: 76 - 23 to the nearest 10 is about 60.
8. Grade 4 estimate: 489 + 112 to the nearest 100 is about 600.
9. In Grade 4, 6,051 rounded to the nearest 1,000 is 6000.
