Too Big, Too Small or Just Right
Test each guess: multiply, then subtract. Circle too big, too small or just right. Then write the right digit.

How to do it
- Multiply the guess by the divisor and subtract.
- Circle too big, too small or just right.
- Write the right digit.
Teaching tip
When a guess is too big, there's nothing to subtract from. When it's too small, another group of the divisor still fits. This sheet is aligned with Common Core 5.NBT.B.6.
About this worksheet
Division steps with a guessed digit to test, a mix of guesses that are too big, too small and just right. Fewer has 5, Standard has 6 and More has 8. Includes an answer key.
What kids practice
Fifth graders divide numbers up to four digits by two-digit numbers, like 864 ÷ 32. The steps are the same as in 4th grade (divide, multiply, subtract, bring down), but each digit of the answer is now a guess. Rounding the divisor helps, and sometimes the guess is one too big or one too small and needs fixing. Partial quotients, taking away easy groups like 10 or 50 of the divisor, is another way to divide that shows why it works.
Watch for
- Keeping a guess that's too small, so what's left is as big as the divisor or bigger.
- Forgetting to write a 0 in the quotient when the divisor doesn't fit after bringing down a digit.
- Writing the first quotient digit above the wrong place.
- Getting a remainder and not deciding what it means in a word problem.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full division with two-digit divisors guide for 5th grade.
