Set 1. Prints on its own sheet.
It practices using two attributes at once — 6 questions for Kindergarten, all on Common Core K.G.B.4: Compare shapes and describe how they are alike and different. 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.B.4 — K.G.B.4, under Geometry for Kindergarten. The published standard reads: “Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts, and other attributes.” The worksheet assesses that standard rather than a paraphrase of it.
Corners and Sides Together is written for Kindergarten, typically ages 5-6. It is one of the sheets on K.G.B.4, 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. Corners and Sides Together, 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.
