Add 2 Digit 1 Digit Numbers Missing Addend No Regrouping Practice Activities
Class 1 printable maths activities for finding the missing 1-digit addend in 2-digit plus 1-digit addition without regrouping.
Practice that builds confidence
What children learn
These Class 1 addition worksheets help children find the missing addend in sums such as 23 + __ = 27 or __ + 4 = 36. The focus is on 2-digit and 1-digit numbers where no regrouping is needed, so children can build confidence with place value and simple addition facts.
The printable activities include missing-number equations, number bonds, visual supports, and structured practice that moves from guided thinking to independent solving. Children practise reading the whole equation, comparing numbers, and deciding what number is needed to complete the sum.
Children practise a key early algebra idea: an addition sentence can have a missing part. Instead of only solving 32 + 5, they learn to solve 32 + __ = 37 by asking, “What was added?” Because there is no regrouping, the tens digit stays the same and children can focus on the ones place.
Progression in these activities
The worksheets begin with clear equations where the 2-digit number comes first, then include missing addends in different positions. Children may see examples like 41 + __ = 46 or __ + 3 = 58. This variety helps them understand that the blank is not always at the end and that the equal sign means “same value as,” not simply “write the answer.”
Parent routine at home
Use a small daily routine with objects or fingers for the 1-digit part. Say, “Start at 24. Count on until you reach 29. How many counts?” Let the child touch one finger for 25, 26, 27, 28, 29 and answer 5. Then write 24 + 5 = 29. Encourage your child to check by adding the missing number back into the original sum.
Classroom use for teachers
Teachers can use these printables for addition revision, maths centres, early-finisher work, or small-group support. They are useful after children have practised basic addition facts and 2-digit plus 1-digit addition without carrying. A teacher can model one question on the board, ask pupils to circle the start number and the total, and then solve the difference in the ones place.
Common mistakes to watch for
Some children add all visible digits and ignore the blank, writing an answer instead of a missing addend. Others compare only the tens digits or count one step too many when counting on. Remind them that the missing number must make the whole equation true. In no-regrouping questions, the ones digit of the total will be greater than or equal to the ones digit of the 2-digit addend.

Helpful answers
Frequently asked questions
What does missing addend mean in Class 1 addition?
A missing addend is the number that has to be added to make the sum correct. For example, in 25 + __ = 29, the missing addend is 4.
Why are these worksheets labelled no regrouping?
No regrouping means the addition does not require carrying to the tens place. Children can solve mainly by comparing the ones digits or by counting on.
How can my child solve 43 + __ = 48?
Ask the child to start at 43 and count on until 48: 44, 45, 46, 47, 48. There are 5 steps, so the missing addend is 5.
Are these worksheets suitable before subtraction is taught?
Yes. Children can solve them by counting on, using fingers, number bonds, or simple visual supports. They do not need formal subtraction methods first.
What mistake should I correct first?
The most important mistake is treating the blank as the final answer. Help the child read the full equation and ask, “What number must go in the blank to make both sides equal?”
