Grade 5 learners deepen rounding fluency in this worksheet, working with larger whole numbers up to four digits and decimal rounding to the nearest whole number. Front-end estimation practice extends into three-digit subtraction problems. Sentence correction items spotlight common rounding errors so students learn to self-check their work. Money contexts reinforce realistic application of estimation in everyday Grade 5 classroom and home mathematics situations and homework.

Estimation Strategies
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Rounded to the nearest 1000, 4,621 is 4,000.
Rewrite: Rounded to the nearest 1000, 4,621 is 5,000.
2. Fix the sentence:
Front-end estimate of 312 + 489 is 3 + 4 = 7.
Rewrite: Front-end estimate of 312 + 489 is 300 + 400 = 700.
3. Fix the sentence:
Rounded to the nearest whole, 8.4 is 9.
Rewrite: Rounded to the nearest whole, 8.4 is 8.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Rounded to the nearest 100, 850 is 900.
2. Rounded to the nearest 1000, 7,238 is 7,000.
3. Front-end estimate of 612 - 198 is 400.
4. Rounded to the nearest 10, $34 is about $30.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Estimate 487 + 612 by rounding each to the nearest 100.
500 + 600 = 1,100
2. Estimate $19.75 + $8.40 to the nearest dollar.
$20 + $8 = $28
