Adding 2 Digit Plus Three 1 Digit Practice Activities
Printable Class 2 maths worksheets for adding one 2-digit number and three 1-digit numbers using place value, regrouping, and careful step-by-step addition.
Practice that builds confidence
Building from known facts
These Class 2 addition worksheets help children practise adding a 2-digit number with three 1-digit numbers, such as 24 + 6 + 3 + 5. The focus is on understanding ones and tens, making careful sums, and deciding when regrouping is needed.
The printable activities include vertical and horizontal addition formats, mixed sums, missing-number style practice, and word-based questions where children combine several small quantities with one larger number.
Children already know many 1-digit addition facts. This worksheet set uses those facts in a longer sum: one 2-digit number plus three 1-digit numbers. A child may add 32 + 4 + 5 + 6 by first adding the ones, then combining the total with the tens. This strengthens number sense instead of treating addition as only a written procedure.
Place value and regrouping
The key idea is that the 2-digit number has tens and ones. In 47 + 2 + 3 + 4, children add 7 + 2 + 3 + 4 in the ones place. If the ones total crosses 10, they regroup 10 ones as 1 ten. The worksheets give practice with sums that do and do not require carrying, so learners see why the carried ten matters.
A useful routine at home
Sit with your child for a short written practice session. Ask them to circle the three 1-digit numbers, add them first, and then add that total to the 2-digit number. For example, in 28 + 3 + 4 + 2, they can think 3 + 4 + 2 = 9, then 28 + 9 = 37. Encourage them to say the steps aloud: “ones first, then tens.”
Classroom practice ideas
Teachers can use these pages for morning maths, independent practice, small-group correction, or addition revision after teaching regrouping. The same worksheet can support different learners: some may use place value blocks or a number line, while others solve mentally and then show the vertical working.
Common mistakes to watch for
Some children add only two numbers and forget the third 1-digit addend. Others carry a ten but do not add it to the tens column, or they write the ones total without regrouping. In horizontal sums, spacing can also confuse learners. Ask them to underline each addend and check that every number has been used once.

Why iBloom worksheets help

Helpful answers
Frequently asked questions
What skill do these Class 2 worksheets practise?
They practise adding one 2-digit number with three 1-digit numbers, helping children combine several addends while using ones, tens, and regrouping when needed.
Should children add the 1-digit numbers first?
Yes, that is often a helpful strategy. For a sum like 35 + 2 + 4 + 3, children can add 2 + 4 + 3 = 9 and then add 9 to 35.
Do these worksheets include carrying?
The practice can include sums where the ones total becomes 10 or more, so children learn to regroup 10 ones as 1 ten in a meaningful way.
How can I help my child avoid missing an addend?
Ask your child to tick or underline each number after using it. This simple check is especially useful when there are four numbers in one addition sum.
Are these worksheets useful for classroom revision?
Yes. Teachers can use them after teaching 2-digit addition, for maths centres, homework, small-group support, or quick revision of addition with multiple addends.
