Adding 2 Digit Plus 1 Digit Practice Activities
Printable Grade 2 activities for adding a 2-digit number and a 1-digit number using place value, mental math, and regrouping practice.
Practice that builds confidence
Build from place value
These Grade 2 addition worksheets help children practise adding a 2-digit number and a 1-digit number, such as 34 + 5 or 47 + 8. Students strengthen place value understanding as they add ones first, decide when a new ten is made, and write accurate sums.
The printable activities include clear number problems, mixed practice, and space for children to show thinking with tens and ones, number lines, or mental math. They are useful for review after classroom lessons, extra fluency practice at home, or small-group support.
Adding a 2-digit number plus a 1-digit number is a key Grade 2 step because children must keep the tens value steady while working with the ones. In 32 + 6, the 3 tens stay the same and 2 ones become 8 ones. In 38 + 6, 8 ones and 6 ones make 14 ones, so children regroup 10 ones as 1 ten and write 44.
Move from models to mental math
These worksheets support a natural progression: first counting ones, then using tens-and-ones drawings or base-ten blocks, then solving with equations. Children may also use an open number line, jumping from 46 to 50 and then to 53 for 46 + 7. Helpful vocabulary includes addend, sum, ones, tens, regroup, and make a ten.
A simple parent routine
At home, choose a short row of problems and ask your child to read each equation aloud. For one problem, have them explain: “How many ones do I have altogether?” and “Do I need to make a new ten?” Encourage them to circle the ones digits before solving. After the row is finished, pick one answer and check it together with quick mental math or a small drawing.
Classroom uses
Teachers can use these printables for morning work, math centers, partner checking, or a quick regrouping review before moving into larger addition. They also work well for small groups: one group can solve with place value charts, another with number lines, and a third can focus on mental strategies such as making ten.
Common errors to watch for
Some children add the 1-digit number to the tens digit instead of the ones digit, turning 42 + 5 into 92 or 47. Others forget to regroup when the ones total is 10 or more, as in 56 + 7. Watch for reversed digits, skipped counts, and answers that are close but not reasonable.

Why iBloom worksheets help
The practice is focused on one exact skill, so children are not distracted by unrelated operations. Problems are arranged to build confidence with easier sums, then strengthen accuracy with regrouping. A child-friendly strategy is: “Add the ones, make a ten if you can, then count the tens.”
Helpful answers
Frequently asked questions
What skill do these Grade 2 worksheets focus on?
They focus on adding a 2-digit number and a 1-digit number, including problems where children do and do not need to regroup ones into a new ten.
Should my child use fingers, drawings, or mental math?
All three can be useful at different stages. For this skill, encourage drawings, base-ten thinking, or a number line so your child connects counting to place value.
How can I tell if my child understands regrouping?
Ask them to explain what happens when the ones add to 10 or more. A strong explanation might be, “I made 10 ones into 1 ten, then added it to the tens.”
What is a common mistake in 2-digit plus 1-digit addition?
A common mistake is adding the 1-digit number to the tens digit instead of the ones digit. For example, in 43 + 6, children should add 3 + 6 first, not 4 + 6.
How can teachers use these worksheets in class?
Teachers can use them for independent practice, math centers, small-group reteaching, exit checks, or partner work after teaching ones, tens, and regrouping.
