Add 2 Digit Plus 1 Digit Missing Addend No Regrouping Practice Activities
Class 2 maths worksheets for finding the missing 1-digit addend in 2-digit plus 1-digit addition without regrouping.
Practice that builds confidence
What this skill covers
These Class 2 addition worksheets help children find the missing addend in sums such as 24 + __ = 29 or __ + 6 = 47. The focus is on 2-digit plus 1-digit addition where the ones do not cross ten, so children can reason without carrying.
The printable activities include balanced practice with blanks in different positions, number sentences, and simple mental maths opportunities. Children strengthen place value, counting on, and subtraction-as-checking while staying within no-regrouping addition.
In this worksheet set, children practise missing addend questions in 2-digit plus 1-digit addition with no regrouping. They may see the blank after the plus sign, before the plus sign, or within a related number sentence. For example, in 32 + __ = 37, the child thinks, “What must be added to 32 to reach 37?” Because the ones stay within the same ten, the work stays focused on understanding the addend rather than carrying.
Building the concept step by step
The progression moves from recognising the known numbers to finding the difference in the ones place. Children can use counting on, number lines, place value blocks, or quick mental maths. They learn that 45 + 3 = 48 also means 48 - 45 = 3, so addition and subtraction are connected. Useful vocabulary includes addend, sum, missing number, ones, tens, and no regrouping.
A simple parent routine
At home, ask your child to read the full sum aloud before writing anything. Cover the blank with a finger and say, “Start at the 2-digit number and count on to the total.” For 61 + __ = 65, let the child count 62, 63, 64, 65 on fingers and notice that four steps were taken. After answering, ask them to check by adding the missing number back into the original sum.
Classroom uses for teachers
Teachers can use these printables for addition revision, maths centres, morning practice, or small-group support. The mixed blank positions are helpful for spotting whether pupils understand the structure of an equation or are only following a left-to-right pattern. Pair work also works well: one child explains the counting-on strategy while the other verifies the answer.
Common errors to watch for
Some children add both visible numbers again, write the total in the blank, or ignore whether the blank is the first or second addend. Others count the starting number as step one, which gives an answer that is one too large. Encourage them to count the jumps, not the numbers said, and to check that the final sum matches the number after the equals sign.

Why iBloom worksheets help
iBloom worksheets keep the practice narrow and purposeful: 2-digit plus 1-digit, missing addend, no regrouping. This lets children build fluency without being distracted by carrying. A child-friendly strategy is: read the sum, start at the known addend, count on to the total, write the number of jumps, then check by adding.
Helpful answers
Frequently asked questions
What does missing addend mean in these Class 2 worksheets?
A missing addend is the number that has to be added to make the given total. For example, in 34 + __ = 39, the missing addend is 5.
Do these worksheets include carrying or regrouping?
No. The questions are designed for 2-digit plus 1-digit addition without regrouping, so the ones total does not cross ten.
How should my child solve 56 + __ = 59?
They can start at 56 and count on to 59: 57, 58, 59. Since that is 3 jumps, the missing addend is 3.
Why are blanks placed in different parts of the sum?
Changing the blank position helps children understand the whole equation, not just a fixed pattern. It also prepares them to solve both __ + 4 = 28 and 28 = 24 + __.
What mistake is most common in missing addend addition?
Many children write the total in the blank or count the starting number as the first jump. Reminding them to count only the jumps usually helps.
