Questions about Sort the Solids

What does the Sort the Solids worksheet cover?

It practices sorting solids by flat faces only against a curved surface — 5 questions for Grade 2, all on Common Core 2.G.A.1: Recognize and draw shapes by their number of sides 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 Sort the Solids practice?

CCSS.MATH.CONTENT.2.G.A.1 — 2.G.A.1, under Geometry for Grade 2. The published standard reads: “Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Sort the Solids is written for Grade 2, typically ages 7-8. It is one of the sheets on 2.G.A.1, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Sort the Solids 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 Sort the Solids 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 Sort the Solids free to print and photocopy?

Yes. Sort the Solids, 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.
