Adding 2 Digit Plus 1 Digit Practice Activities
Printable Class 2 maths worksheets for practising two-digit plus one-digit addition with place value, counting on, and carrying where needed.
Practice that builds confidence
What children learn
These Class 2 maths worksheets help children practise adding a 2-digit number and a 1-digit number, such as 34 + 5 or 47 + 8. The focus is on understanding ones and tens, not just getting the answer quickly.
The printable activities include sums in different formats so children can build confidence with mental addition, vertical addition, and regrouping when the ones add up to 10 or more.
Children strengthen the idea that a 2-digit number has tens and ones. In 36 + 4, they learn to add 4 to the ones digit first. In 58 + 7, they see that 8 ones + 7 ones makes 15 ones, so 10 ones become 1 ten. This prepares them for larger addition later.
How the practice progresses
The worksheets can be used from easier sums without carrying, such as 42 + 3, to sums where carrying is needed, such as 76 + 8. Children may meet horizontal sums, column sums, missing-answer questions, and mixed practice. This variety helps them recognise that the same addition idea works in different layouts.
Parent routine at home
Start with five oral sums using small 1-digit addends. Ask your child to say the tens and ones: “46 has 4 tens and 6 ones.” Then let them solve one row of the worksheet. For tricky sums, use bundles of ten sticks, buttons, or a number line. End by asking your child to explain one answer in words, for example, “29 + 6 becomes 35 because 9 + 6 is 15.”
Classroom use for teachers
Teachers can use these sheets for independent practice after demonstrating place-value addition on the board. They also work well in maths centres, small-group revision, quick checks after a lesson, or homework. Mixed pages are useful for spotting who is ready for regrouping and who still needs support with ones and tens.
Common errors to watch for
Some children add the 1-digit number to the tens digit instead of the ones digit, writing 46 + 3 as 76. Others forget to carry when the ones make more than 9, or they reverse digits after regrouping. Encourage neat column alignment and ask children to underline the ones column before solving.

Helpful answers
Frequently asked questions
What skill do these worksheets practise?
They focus on adding a 2-digit number to a 1-digit number, helping Class 2 children add the ones correctly and understand when carrying is needed.
Do these worksheets include addition with carrying?
Yes, the practice can include sums where the ones add up to 10 or more, such as 47 + 8, so children learn to regroup 10 ones as 1 ten.
How can I help my child if they keep adding to the tens digit?
Ask your child to circle the ones digit in the 2-digit number before adding. For 52 + 6, they should add 2 + 6 first, then keep the 5 tens.
