Questions about Turn It Around

What does the Turn It Around worksheet cover?

It practices commutativity of multiplication, shown as a pair — 10 questions for Grade 3, all on Common Core 3.OA.B.5: Use known facts and patterns to work out harder ones. The instruction to students is “Fill in both blanks”, and the answer key follows on the next sheet.

Which Common Core standard does Turn It Around practice?

CCSS.MATH.CONTENT.3.OA.B.5 — 3.OA.B.5, under Operations & Algebraic Thinking for Grade 3. The published standard reads: “Apply properties of operations as strategies to multiply and divide.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Turn It Around is written for Grade 3, typically ages 8-9. It is one of the sheets on 3.OA.B.5, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Turn It Around come with an answer key?

Yes. All 10 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 Turn It Around 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 Turn It Around free to print and photocopy?

Yes. Turn It Around, 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.

Is there a lesson plan to teach 3.OA.B.5?

Yes — “Properties of Multiplication” is a 45-minute Grade 3 plan for 3.OA.B.5, timed section by section, with the misconceptions to expect and an exit ticket. Turn It Around is the practice that follows it.
