Questions about Sort Shapes by Sides

What does the Sort Shapes by Sides worksheet cover?

It practises classifying shapes by side count — 5 questions for Kindergarten, all on Common Core K.G.A.1: Name shapes you see and say where things are — above, below, next to. 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 Sort Shapes by Sides practise?

CCSS.MATH.CONTENT.K.G.A.1 — K.G.A.1, in the Geometry domain for Kindergarten. The published standard reads: “Describe objects in the environment using names of shapes, and describe the relative positions of these objects.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Does Sort Shapes by Sides 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.

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.
