Questions about Rows of Two

What does the Rows of Two worksheet cover?

It practises doubling as equal groups — 7 questions for Grade 2, all on Common Core 2.OA.C.4: Add equal rows to find a total — the first step toward multiplication. The instruction to pupils is “Work out each answer”, and the answer key follows on the next sheet.

Which Common Core standard does Rows of Two practise?

CCSS.MATH.CONTENT.2.OA.C.4 — 2.OA.C.4, in the Operations & Algebraic Thinking domain for Grade 2. The published standard reads: “Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Rows of Two is written for Grade 2, typically ages 7-8. It is one of the sheets on 2.OA.C.4, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does Rows of Two come with an answer key?

Yes. All 7 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 Rows of Two can I print?

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.

Is Rows of Two free to print and photocopy?

Yes. Rows of Two, 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.
