Questions about Order the Teen Numbers

What does the Order the Teen Numbers worksheet cover?

It practices the teen sequence — 8 questions for Kindergarten, all on Common Core K.NBT.A.1: See the teen numbers as a ten plus some extra ones. The instruction to students is “Write the missing numbers”, and the answer key follows on the next sheet.

Which Common Core standard does Order the Teen Numbers practice?

CCSS.MATH.CONTENT.K.NBT.A.1 — K.NBT.A.1, under Number & Operations in Base Ten for Kindergarten. The published standard reads: “Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Does Order the Teen Numbers 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.

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.
