Questions about Equal Parts or Not?

What does the Equal Parts or Not? worksheet cover?

It practices the requirement that parts be equal — 5 questions for Grade 1, all on Common Core 1.G.A.3: Split shapes into halves and quarters. 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 Equal Parts or Not? practice?

CCSS.MATH.CONTENT.1.G.A.3 — 1.G.A.3, under Geometry for Grade 1. The published standard reads: “Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Equal Parts or Not? is written for Grade 1, typically ages 6-7. It is one of the sheets on 1.G.A.3, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Equal Parts or Not? 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 Equal Parts or Not? 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 Equal Parts or Not? free to print and photocopy?

Yes. Equal Parts or Not?, 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.
