It practices writing a division as a fraction and a fraction as a division — 12 questions for Grade 5, all on Common Core 5.NF.B.3: Understand a fraction as a division, and solve sharing problems whose answers are fractions or mixed numbers. The instruction to students is “Fill in the missing part”, and the answer key follows on the next sheet.
CCSS.MATH.CONTENT.5.NF.B.3 — 5.NF.B.3, under Number & Operations — Fractions for Grade 5. The published standard reads: “Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.” The worksheet assesses that standard rather than a paraphrase of it.
Fractions as Division is written for Grade 5, typically ages 10-11. It is one of the sheets on 5.NF.B.3, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.
Yes. All 12 answers are generated from the same problems as the questions, so the key cannot drift out of step with the sheet. It starts on a fresh sheet of paper, after the questions, so it is not handed out with the class by accident.
25 — one per student, and all 25 ask different questions. Set 1 downloads the whole class as a single PDF. Every version is fixed to its own address, so a sheet printed today holds the same problems when you reopen it next week.
Yes. Fractions as Division, its answer key and its 25 versions are free to print and photocopy for your own class, with no account, no email capture and no subscription at the download step. Please do not resell them or republish them as your own.
