Set 1. Prints on its own sheet.
It practices counting vertices — 6 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 students is “How many corners does each shape have?”, and the answer key follows on the next sheet.
CCSS.MATH.CONTENT.K.G.A.1 — K.G.A.1, under Geometry 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.
How Many Corners? is written for Kindergarten, typically ages 5-6. It is one of the sheets on K.G.A.1, so it suits any student working at that standard — including older students 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 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.
Yes. How Many Corners?, 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.
