Set 1. Prints on its own sheet.
It practises carrying across more than one addend — 10 questions for Grade 2, all on Common Core 2.NBT.B.5: Add and subtract within 100 confidently. The instruction to pupils is “Work out each answer”, and the answer key follows on the next sheet.
CCSS.MATH.CONTENT.2.NBT.B.5 — 2.NBT.B.5, in the Number & Operations in Base Ten domain for Grade 2. The published standard reads: “Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.” The worksheet assesses that standard rather than a paraphrase of it.
Add Three Two-Digit Numbers is written for Grade 2, typically ages 7-8. It is one of the sheets on 2.NBT.B.5, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.
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.
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.
Yes. Add Three Two-Digit Numbers, 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.
