Questions about Line Plots — Halves and Quarters

What does the Line Plots — Halves and Quarters worksheet cover?

It practices the difference between lengths, and the total at one length, on a plot in quarters — 4 questions for Grade 4, all on Common Core 4.MD.B.4: Make line plots of measurements in halves, quarters and eighths, and add and subtract fractions to answer questions about them. The instruction to students is “Use the line plot to answer”, and the answer key follows on the next sheet.

Which Common Core standard does Line Plots — Halves and Quarters practice?

CCSS.MATH.CONTENT.4.MD.B.4 — 4.MD.B.4, under Measurement & Data for Grade 4. The published standard reads: “Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Line Plots — Halves and Quarters is written for Grade 4, typically ages 9-10. It is one of the sheets on 4.MD.B.4, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Line Plots — Halves and Quarters come with an answer key?

Yes. All 4 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.

How many different versions of Line Plots — Halves and Quarters can I print?

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.
