CCSS.MATH.CONTENT.4.MD.C.5 — 4.MD.C.5, in the Measurement & Data domain for Grade 4. The published standard reads: “Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement.” The worksheet assesses that standard rather than a paraphrase of it.
Measure the Angle is written for Grade 4, typically ages 9-10. It is one of the sheets on 4.MD.C.5, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.
Yes. All 8 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 pupil, 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.
