Questions about Symmetrical or Not?

What does the Symmetrical or Not? worksheet cover?

It practises deciding whether a figure has symmetry — 5 questions for Grade 4, all on Common Core 4.G.A.3: Find lines of symmetry. The instruction to pupils is “Sort each one into the right box”, and the answer key follows on the next sheet.

Which Common Core standard does Symmetrical or Not? practise?

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.

What age or grade is this worksheet for?

Symmetrical or Not? 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.

Does Symmetrical or Not? 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 Symmetrical or Not? can I print?

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.

Is Symmetrical or Not? free to print and photocopy?

Yes. Symmetrical or Not?, 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.

Is there a lesson plan to teach 4.G.A.3?

Yes — “Lines of Symmetry” is a 50-minute Grade 4 plan for 4.G.A.3, timed section by section, with the misconceptions to expect and an exit ticket. Symmetrical or Not? is the practice that follows it.
