This Grade 2 estimation worksheet puts rounding to work inside real classroom and everyday stories. Four multiple-choice word problems ask students to estimate sums and differences and to check if answers are reasonable after the work is done. Five fill-in questions walk through the rounded sums step by step so the method stays clear. Grade 2 readers practice the habit of estimating first before trusting any exact answer they compute today.

Estimation (Intro)
Part A: Multiple Choice
Circle the best answer for each question.
1. A class has 28 red crayons and 33 blue crayons. About how many crayons in all?
A) About 60
B) About 40
C) About 90
D) About 100
2. Maya read 47 pages Monday and 52 pages Tuesday. Her total was 99. Is that reasonable?
A) Yes, estimate is about 100
B) No, estimate is about 50
C) No, estimate is about 150
D) No, estimate is about 200
3. A farm has 61 hens and 18 ducks. Which estimate of the total birds is best?
A) About 80
B) About 50
C) About 100
D) About 40
4. Leo had 82 stickers and gave away 39. He said he has 43 left. Is that reasonable?
A) Yes, estimate is about 40
B) No, estimate is about 60
C) No, estimate is about 20
D) No, estimate is about 80
Part B: Fill in the Blank
Write the correct answer on each line.
1. If 28 + 33 rounds to 30 + 30, the estimate is 60.
2. Rounded estimate of 47 + 52 is 50 + 50 = 100.
3. Rounded estimate of 61 + 18 is 60 + 20 = 80.
4. Rounded estimate of 82 - 39 is 80 - 40 = 40.
5. Estimation helps you quickly check if an answer is reasonable.
