Set 1. Prints on its own sheet.
It practices producing a position rather than reading one — 6 questions for Grade 3, all on Common Core 3.NF.A.2: Place fractions on a number line. The instruction to students is “Mark each fraction on the line”, and the answer key follows on the next sheet.
CCSS.MATH.CONTENT.3.NF.A.2 — 3.NF.A.2, under Number & Operations — Fractions for Grade 3. The published standard reads: “Understand a fraction as a number on the number line; represent fractions on a number line diagram.” The worksheet assesses that standard rather than a paraphrase of it.
Mark the Fraction is written for Grade 3, typically ages 8-9. It is one of the sheets on 3.NF.A.2, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.
Yes. All 6 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. Mark the Fraction, 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.
