Horizontal No Regroup 2X1 Digits Practice Activities
Printable math drill worksheets for practicing horizontal 2-digit plus 1-digit addition without regrouping.
Practice that builds confidence
What the skill includes
Children practise adding a 1-digit number to a 2-digit number in horizontal form, such as 34 + 5. Because the problems do not require regrouping, students can focus on place value, counting on, and building mental addition fluency.
The printable activities include clear rows of addition facts designed for repeated, confident practice. They fit well after children know tens and ones and are ready to solve 2-digit plus 1-digit equations without stacking.
These worksheets focus on 2-digit plus 1-digit addition written across the page, such as 34 + 5 or 72 + 6. Because every problem is no regrouping, the ones digits make a sum less than 10. Children practise seeing that the tens stay the same while the ones increase.
How understanding builds
Start by reading each equation left to right and identifying the 2-digit addend. Children can picture tens rods and ones cubes, a hundred chart move, or expanded form: 43 + 5 means 4 tens and 3 ones plus 5 more ones. The horizontal layout encourages mental addition instead of relying only on stacking digits.
Parent routine
Choose one short page and ask your child to circle the ones digit in the 2-digit number before solving. Have them say, “Add the ones; keep the tens,” then write the sum. After every row, invite a quick check: Is the answer still in the same ten? For 61 + 7, the answer should be in the 60s because 1 + 7 does not make a new ten.
Classroom uses
Teachers can use these pages for warm-ups, fluency folders, math centers, or quick checks after a lesson on place value addition. Pair a worksheet with base-ten blocks for students who need support, or use the same page as a mental-math challenge for students who are ready. Partners can trade papers and explain one answer using tens and ones vocabulary, not just “I counted.”
Common errors to watch for
Some children add the 1-digit number to the tens place, writing 34 + 5 = 84. Others forget that a horizontal problem still has place value, or they count on but skip a number. Watch also for answers that cross into the next ten, such as 48 + 1 = 59, which signals weak place-value checking.

Why iBloom worksheets help
iBloom practice keeps the task focused: 2-digit plus 1-digit, horizontal, no regrouping. A helpful child strategy is: “Find the ones, add the little number, then bring the tens along.” In 26 + 3, solve 6 + 3 = 9, then place it after the 2 tens to make 29.
Helpful answers
Frequently asked questions
What does 2x1 digits mean on these addition worksheets?
It means each problem adds a 2-digit number and a 1-digit number, such as 42 + 6. The equations are written horizontally rather than stacked vertically.
Do these worksheets include regrouping or carrying?
No. The ones digits are chosen so children do not need to make a new ten. For example, 53 + 4 is included, but 57 + 8 would require regrouping and is not the focus here.
Why use horizontal addition instead of vertical addition?
Horizontal addition helps children think about the whole number and use place value mentally. It builds the idea that in 64 + 3, only the ones increase while the tens remain 6 tens.
How can I help my child check answers?
Ask your child to check whether the answer stays in the same ten. For 72 + 5, the answer should still be in the 70s because 2 + 5 does not reach 10.
What should a child know before starting this practice?
Children should understand tens and ones, recognize 2-digit numbers, and be comfortable adding small 1-digit numbers. Counting on and using simple place value language are helpful.
