Item details
Estimate Sums and Differences is a 12-page practice pack for Grades 3-4. Round both operands to the requested place before estimating the result.
It contains 96 numbered tasks. Activity sections: Estimate Sums: Nearest Ten; Estimate Differences: Nearest Hundred.
Sheet 1, first task: Round each number first. Then add the rounded numbers to get an estimate. Answer: 450 + 800 = 1,250. Sheet 7, first task: Round each number first. Then add the rounded numbers to get an estimate. Answer: 3,670 + 6,430 = 10,100. Sheet 12, first task: Round each number first. Then subtract the rounded numbers to get an estimate. Answer: 55,600 − 45,700 = 9,900.
Everything arrives in one ZIP: a 12-page worksheet PDF and a 2-page answer-key PDF in US Letter, plus the matching two PDFs in A4. Answers use exact arithmetic, and the key follows the sheet and question numbers. Student answer spaces are left empty for writing.
