Set 1. Prints on its own sheet.
It practises 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 pupils 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, in the Number & Operations — Fractions domain 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 pupil working at that standard — including older pupils 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 versions, of which 24 ask genuinely different questions — this skill does not have 25 distinct questions to give, so the rest reorder them and no two pupils still share a paper. Set 1 downloads all 25 as one PDF.
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.
