Practice that builds confidence
What children are learning
These Grade 1 printable math worksheets help children solve missing-addend equations with two 2-digit numbers, such as 24 + ___ = 57 or ___ + 13 = 46. The focus is addition without regrouping, so children can reason with tens and ones before carrying is introduced.
Activities give practice reading number sentences, finding the unknown addend, and checking answers by adding. Children see missing numbers in different positions and build confidence using place value, related subtraction, and careful digit alignment.
Missing-addend work turns addition into a thinking task: one part and the total are known, and the other part must be found. Because all problems use 2-digit numbers with no regrouping, children can separate tens and ones cleanly. For example, in 32 + ___ = 58, they can notice that 2 ones need 6 more ones, and 3 tens need 2 more tens, so the missing addend is 26.
How the practice progresses
The worksheets move children beyond simply adding two given numbers. Problems may appear horizontally or vertically, with the blank in the first or second addend. This helps students understand that the missing number is not always at the end of the equation. The main vocabulary to reinforce is addend, sum, missing number, tens, ones, and no regrouping.
Parent practice routine
At home, choose a few problems and ask your child to read each equation aloud. Have them underline the total, circle the known addend, and say what must be found. If needed, draw quick tens sticks and ones dots. After writing the missing addend, your child should check by adding the two addends to see whether the sum matches.
Classroom uses for teachers
Teachers can use these pages for small-group place value practice, morning work, math centers, or a quick exit check after teaching related facts. They are also useful for students who can add 2-digit numbers but need more experience interpreting an equation with a blank.
Common errors to watch for
Some children copy the sum into the blank, subtract digits in the wrong order, or treat the tens and ones as unrelated numbers. Others line up digits poorly in vertical problems. Remind them that each digit has a place: ones solve with ones, and tens solve with tens.

Helpful answers
Frequently asked questions
What does no regrouping mean in these worksheets?
No regrouping means the ones digits and tens digits can be worked out without carrying to the next place. This lets Grade 1 children focus on the missing addend and place value.
How can my child find the missing addend?
Have your child identify the sum, look at the known addend, then find how many ones and tens are needed to reach the total. They can check by adding the known addend and the missing addend.
Are the blanks always in the same position?
No. Practice with the blank in different addend positions helps children understand the structure of the equation instead of memorizing one layout.
Should Grade 1 students use subtraction for these problems?
They may use related subtraction as a checking or solving strategy, such as thinking 58 minus 32 equals the missing addend. Place value drawings are also helpful.
Why is this skill useful before addition with regrouping?
It strengthens understanding of tens, ones, addends, and sums. Once children can find unknown addends without carrying, they are better prepared for more complex 2-digit addition.
