How to teach place-value based 2-digit addition
- 1
Separate the columns visually
Draw a vertical line between the tens and ones digits so your child solves each column as its own mini addition problem.
- 2
Add ones first, then tens
Establish the habit of always starting with the rightmost column, which sets up the exact routine they'll need later for regrouping.
- 3
Use expanded form as a check
Have them rewrite 34 + 25 as 30 + 20 and 4 + 5, solve each part, then add the partial sums together to confirm their column answer.
- 4
Introduce a hundred chart
A hundred chart lets kids visually track how adding tens moves them down rows while adding ones moves them across a row.
Common mistakes kids make
- Adding a ones digit to a tens digit by mistake — a printed place-value grid on the worksheet keeps columns aligned.
- Writing the tens digit before the ones digit — always work right to left, ones column first.
- Losing track of which number is which when copying problems onto blank paper — keep them working directly on the printed sheet.
- Skipping zero placeholders, like writing 5 instead of 05 in a column — practice with a couple of zero-containing examples early on.
Tips for parents and teachers
- This is a great pre-test to confirm a child is ready for the regrouping worksheet.
- Use two different colored pencils, one for tens and one for ones, to reinforce the column separation.
- Keep numbers under 100 so mental math stays manageable at this stage.
- Praise correct column alignment as much as correct final answers.

Open worksheetFrequently asked questions
What's the difference between addition with and without regrouping?
Without regrouping, each column's sum stays under 10, so there's never a ten to carry; with regrouping, at least one column sums to 10 or more.
What grade level is this for?
Non-regrouping 2-digit addition is commonly practiced in 1st grade and reviewed at the start of 2nd grade.
Why practice without regrouping before regrouping?
It lets kids master column alignment and place value first, so the added skill of carrying doesn't overwhelm them all at once.
Do these worksheets include an answer key?
Yes, every printable PDF comes with a matching answer key for quick, independent checking.
How can I tell if my child is ready for regrouping practice?
If they consistently solve no-regrouping problems accurately and quickly, they're ready to try the regrouping worksheet next.
Can I use a hundred chart with these problems?
Yes, a hundred chart is a helpful visual for showing how adding tens and ones moves a number around the grid.
