Grade 2 Addition Worksheets — Free Printable PDF
Free Grade 2 addition worksheets — two-digit addition with regrouping, three-digit addition, mental math strategies. Common Core 2.NBT aligned.
Grade 2 addition is where the number columns start to matter. A child who could add single-digit numbers in their head now has to learn place value notation, line up the ones and tens, and handle the strange but essential trick of carrying. Regrouping (the official name for carrying) trips up many Grade 2 kids the first few weeks, but it clicks fast with reps.
Our Grade 2 addition sheets walk through it in order: two-digit + one-digit (no regrouping), two-digit + two-digit (no regrouping), then two-digit + two-digit (with regrouping), and finally three-digit + three-digit. We also include mental math strategy sheets — making 10s, breaking apart numbers, using doubles — which the Common Core 2.NBT.B.5 standard explicitly requires.

The new name for 'carrying' in addition — when the ones column adds to more than 9, you regroup 10 ones into a ten and carry it to the tens column.
Should Grade 2 do three-digit addition?+
Yes — Common Core 2.NBT.B.7 expects addition within 1000 by end of Grade 2. Three-digit problems are core curriculum.
What are mental math strategies?+
Tricks for adding without writing it down — like adding to a friendly 10 first, or breaking a number apart. 2.NBT.B.5 requires these.
Are answer keys included?+
