Regular Shapes and Symmetry is a free printable Grade 4 maths worksheet on the link between sides and lines of symmetry, aligned to Common Core standard 4.G.A.3. It prints 6 questions with an answer key on its own sheet of paper, in 25 versions that each ask different questions, so no two pupils in the class work from the same page.

Set 1. Prints on its own sheet.
It practises the link between sides and lines of symmetry — 6 questions for Grade 4, all on Common Core 4.G.A.3: Find lines of symmetry. The instruction to pupils is “How many sides does each shape have?”, and the answer key follows on the next sheet.
CCSS.MATH.CONTENT.4.G.A.3 — 4.G.A.3, in the Geometry domain for Grade 4. The published standard reads: “Recognize a line of symmetry for a two-dimensional figure. Identify line-symmetric figures and draw lines of symmetry.” The worksheet assesses that standard rather than a paraphrase of it.
Regular Shapes and Symmetry is written for Grade 4, typically ages 9-10. It is one of the sheets on 4.G.A.3, 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 — 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.
Yes. Regular Shapes and Symmetry, 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.
