This Grade 4 sheet emphasizes checking answers for reasonableness using estimation. Grade 4 students compare exact computations like 387 + 412 with rounded estimates such as 400 + 400 = 800 to detect unreasonable answers. Multiple-choice and fill-in items combine rounding to the nearest 1,000, estimation of products, and real-world reasonableness checks. Aligned to CCSS 4.NBT.3. Grade 4 students apply real-world reasoning.

B) No, the estimate is about 800
C) No, the estimate is about 1,500
D) Cannot tell
2. A Grade 4 estimate of 612 - 198 to the nearest 100 is closest to which value?
A) 300
B) 400
C) 500
D) 600
3. A school store sold 2,856 pencils. About how many pencils, rounded to the nearest 1,000? (Grade 4)
A) 2,000
B) 3,000
C) 2,800
D) 2,900
4. A Grade 4 student says 528 x 5 is about 3,000. Which estimate did they likely use?
A) 500 x 5 = 2,500
B) 600 x 5 = 3,000
C) 500 x 6 = 3,000
D) 1,000 x 3 = 3,000
Part B: Fill in the Blank
Write the correct answer on each line.
1. Grade 4 estimate: 489 x 4 using rounding is about 2000.
2. A Grade 4 estimate of 7,491 to the nearest 1,000 is 7000.
3. Grade 4 estimate: 3,612 + 5,489 to nearest 1,000 is about 9000.
4. A Grade 4 student finds 612 - 287 = 325. Their estimate to nearest 100 is 300.
5. Grade 4: 4,950 rounded to the nearest 1,000 is 5000.
