Questions about Lines, Rays and Segments

What does the Lines, Rays and Segments worksheet cover?

It practices telling a line, a ray and a line segment apart by their ends — 5 questions for Grade 4, all on Common Core 4.G.A.1: Draw and identify lines, rays and angles. The instruction to students is “Sort each one into the right box”, and the answer key follows on the next sheet.

Which Common Core standard does Lines, Rays and Segments practice?

CCSS.MATH.CONTENT.4.G.A.1 — 4.G.A.1, under Geometry for Grade 4. The published standard reads: “Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Lines, Rays and Segments is written for Grade 4, typically ages 9-10. It is one of the sheets on 4.G.A.1, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Lines, Rays and Segments come with an answer key?

Yes. All 5 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 Lines, Rays and Segments 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.

Is Lines, Rays and Segments free to print and photocopy?

Yes. Lines, Rays and Segments, 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.
