Adding One 2 Digit And Two 1 Digit Numbers Practice Activities
Class 3 maths worksheets for adding one 2-digit number with two 1-digit numbers using place value, regrouping, and careful checking.
Practice that builds confidence
Build from place value
These Class 3 maths practice activities help children add one 2-digit number and two 1-digit numbers, such as 34 + 7 + 5. Learners strengthen place value, counting on, making ten, and regrouping when the ones total crosses 9.
The printable worksheets include clear addition questions arranged for steady practice. Children meet sums in horizontal and column-style formats, giving them chances to choose efficient methods while keeping tens and ones organised.
This skill sits between simple 2-digit addition and larger multi-addend sums. Children learn that the 2-digit number has tens and ones, while each 1-digit number affects the ones place first. For example, in 46 + 8 + 3, the ones are 6, 8, and 3. Since 6 + 8 + 3 = 17, children record 7 ones and regroup 1 ten, making the total 57.
Progression in the practice
The worksheets move from straightforward sums where the ones stay below ten to examples where regrouping is needed. This helps children see why 24 + 2 + 3 feels different from 24 + 8 + 7. They practise reading the whole expression, adding all three numbers, and checking that no addend has been skipped.
Simple routine at home
Ask your child to solve five questions aloud. First, say the tens in the 2-digit number. Next, add the ones and the two 1-digit numbers. Finally, combine the tens and ones. Use everyday numbers, such as “₹36 + ₹4 + ₹5”, to connect the worksheet to real adding. If your child hesitates, let them draw tens sticks and ones dots before writing the answer.
Classroom uses for teachers
Teachers can use these printables for maths warm-ups, independent practice, remedial support, or small-group centres. One group can solve by drawing tens and ones, another can use column addition, and a confident group can explain a mental strategy. The same worksheet also works well for quick observation of who understands regrouping.
Common errors to watch for
Some learners add only two of the three numbers, write 16 as the answer to 48 + 5 + 3, or place the carried ten in the ones column. Others count on from the 2-digit number but lose track of the second 1-digit number. Encourage children to underline all three addends and circle the ones total when it reaches ten or more.
Child-friendly strategy
Try “join the small numbers first.” In 53 + 6 + 4, notice that 6 + 4 makes 10, so 53 becomes 63. When the small numbers do not make ten exactly, add the bigger 1-digit number first, then count on the last number carefully.

Helpful answers
Frequently asked questions
What does adding one 2-digit and two 1-digit numbers mean?
It means solving sums with three addends, where one number is from 10 to 99 and the other two are single-digit numbers, such as 42 + 6 + 7.
Should my child add the 1-digit numbers first?
Often, yes. Adding the two 1-digit numbers first can make the sum easier, especially when they make ten, as in 58 + 4 + 6.
How do these worksheets help with regrouping?
They include sums where the ones total can cross 9, so children practise carrying 1 ten and placing the remaining ones correctly.
Can these activities be used for mental maths?
Yes. Children can solve many questions mentally by counting on or making ten, while still using written working when a sum needs careful regrouping.
What is a common mistake in this skill?
A common mistake is adding only the 2-digit number and one 1-digit number. Children should point to or tick all three addends before writing the final answer.
