Questions about Quadrilaterals

What does the Quadrilaterals worksheet cover?

It practices shapes with four sides, whatever else they have in common — 5 questions for Grade 3, all on Common Core 3.G.A.1: Group shapes by what they have in common. 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 Quadrilaterals practice?

CCSS.MATH.CONTENT.3.G.A.1 — 3.G.A.1, under Geometry for Grade 3. The published standard reads: “Understand that shapes in different categories may share attributes, and that shared attributes can define a larger category.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Quadrilaterals is written for Grade 3, typically ages 8-9. It is one of the sheets on 3.G.A.1, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Quadrilaterals 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 Quadrilaterals 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 Quadrilaterals free to print and photocopy?

Yes. Quadrilaterals, 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 3.G.A.1?

Yes — “Sorting Shapes by Shared Attributes” is a 45-minute Grade 3 plan for 3.G.A.1, timed section by section, with the misconceptions to expect and an exit ticket. Quadrilaterals is the practice that follows it.
