Questions about Doubling Patterns

What does the Doubling Patterns worksheet cover?

It practises a doubling rule rather than an additive one — 5 questions for Grade 3, all on Common Core 3.OA.D.9: Spot and explain number patterns. The instruction to pupils is “Write the rule and the next number”, and the answer key follows on the next sheet.

Which Common Core standard does Doubling Patterns practise?

CCSS.MATH.CONTENT.3.OA.D.9 — 3.OA.D.9, in the Operations & Algebraic Thinking domain for Grade 3. The published standard reads: “Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Doubling Patterns is written for Grade 3, typically ages 8-9. It is one of the sheets on 3.OA.D.9, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does Doubling Patterns 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 Doubling Patterns can I print?

25 versions, of which 21 ask genuinely different questions — this skill does not have 25 distinct questions to give, so the rest reorder them and no two pupils still share a paper. Set 1 downloads all 25 as one PDF.

Is Doubling Patterns free to print and photocopy?

Yes. Doubling Patterns, 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.
