Adding Two Whole Tens And Two 1 Digit Numbers Practice Activities
Class 3 children practise adding two whole tens and two 1-digit numbers by grouping tens and ones, with and without carrying.
Practice that builds confidence
What this skill builds
These Class 3 maths worksheets help children add expressions that contain two whole tens and two 1-digit numbers, such as 30 + 50 + 4 + 7. The focus is on seeing tens and ones separately, then combining them accurately.
The printable activities include mixed addition sums, place-value based practice, missing-number style questions, and space for children to show grouping. They build confidence with mental addition, regrouping ones into a ten, and writing the final total clearly.
Adding two whole tens and two 1-digit numbers is a useful bridge between simple addition and larger 2-digit calculations. Children learn that 40 + 20 can be added as tens first, while 5 + 8 can be added as ones. When the ones make 10 or more, they regroup, so 40 + 20 + 5 + 8 becomes 60 + 13, then 73. This strengthens place value, number sense, and flexible mental maths.
How the practice progresses
The worksheets move from easy combinations where the ones stay below 10 to examples where carrying is needed. Children may first solve 20 + 30 + 2 + 5, then meet sums such as 50 + 30 + 6 + 9. This gradual change helps them notice when ones can be written directly and when 10 ones must become 1 ten.
A simple parent routine
At home, ask your child to read the sum aloud and circle the whole tens. Then let them add the tens, add the 1-digit numbers, and put the parts together. For example: “70 plus 10 is 80; 3 plus 8 is 11; 80 plus 11 is 91.” Encourage them to explain the regrouping rather than only writing the answer.
Classroom uses for teachers
Teachers can use these pages for addition warm-ups, maths centres, small-group reteaching, or quick checks after a place-value lesson. The sums also work well for board discussion: invite pupils to show different methods, such as tens-and-ones grouping, number line jumps, or expanded form.
Common errors to watch for
Some children add all the digits as if they are ones, writing 3 + 5 + 4 + 7 instead of treating 30 and 50 as tens. Others forget to carry when the two 1-digit numbers cross 10. A helpful strategy is: “Tens with tens, ones with ones, then join.” Children can underline tens in one colour and ones in another before solving.

Helpful answers
Frequently asked questions
What does adding two whole tens and two 1-digit numbers mean?
It means adding two multiples of ten, such as 30 and 50, along with two single-digit numbers, such as 4 and 7. Children combine the tens, combine the ones, and then find the total.
Should my child add from left to right or group the numbers first?
For this skill, grouping is usually clearer. Ask your child to add the whole tens together first, add the 1-digit numbers next, and then combine both results.
Do these worksheets include carrying?
Yes, the practice can include sums where the two 1-digit numbers make 10 or more, such as 6 + 8. This helps children understand how ones are regrouped into a ten.
What is a good example to explain this skill at home?
Use a sum like 40 + 20 + 3 + 9. Say: 40 + 20 = 60, 3 + 9 = 12, and 60 + 12 = 72. This shows both tens-and-ones grouping and regrouping.
How can I tell if my child understands the place value part?
Ask them to explain why 30 is 3 tens and not 3 ones. If they can separate tens from ones and describe the regrouping when needed, they are developing the right understanding.
