Questions about Patterns — Counting by Nines

What does the Patterns — Counting by Nines worksheet cover?

It practises the nines pattern in the times table — 8 questions for Grade 3, all on Common Core 3.OA.D.9: Spot and explain number patterns. The instruction to pupils is “Write the missing numbers”, and the answer key follows on the next sheet.

Which Common Core standard does Patterns — Counting by Nines 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?

Does Patterns — Counting by Nines come with an answer key?

Yes. All 8 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 Patterns — Counting by Nines 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.
