Divide whole numbers by a 3-digit number

This page asks for fluent long division when the divisor has three digits.

• Estimate each quotient digit: 1,769 ÷ 570 is about 3, because 3 × 570 = 1,710
• Multiply, subtract and bring down until no digits remain
• Spot an answer of 100 with a remainder: 64,259 ÷ 642 = 100 R 59
• Choose the remainder of 3,016 ÷ 107 from five options

Dividing multi-digit numbers with the standard algorithm is 6.NS.B.2, the last whole-number division standard before decimals.

Print page one and give your child scrap paper: the last three divisions have answer boxes but no working space.

• Round the divisor to estimate each digit: 616 is close to 600.
• Write the quotient in the red box and the remainder in the blue box.
• Check every result by multiplying back and adding the remainder: 68 × 320 + 194 = 21,954.

The second page lists every quotient and remainder.

• Forgetting zeros in the quotient: 64,259 ÷ 642 is 100, not 1 or 10.
• Stopping too early: a remainder of 598 when dividing by 570 means another 1 fits.
• Mixing up the answer and remainder boxes.

Note: on page one, item b has no dividend and its box shows "3,537 ÷ 14" from another sheet; the key solves 1,075 ÷ 215 = 5. Give your child 1,075 ÷ 215. Items a and b also print the quotient digits, and the headings say "estimated" and "tick" where exact answers are written.
