Addition Practice
Adding multi-digit numbers and decimals
Line up the digits by place value, add from the right, and carry when a column totals ten or more. For decimals, line up the decimal points so tenths are added to tenths. Estimate first by rounding, and then compare the exact answer with the estimate.
Worked examples
- 478 + 256: ones 8 + 6 = 14, write 4 and carry 1. Tens 7 + 5 + 1 = 13, write 3 and carry 1. Hundreds 4 + 2 + 1 = 7. The sum is 734.
- 3.6 + 12.45: write 3.60 + 12.45 with the decimal points lined up to get 16.05.
- Estimate 478 + 256 as 500 + 250 = 750. The exact answer, 734, is close, so it is reasonable.
Common slips
- Not carrying, so 14 in the ones column is written as 14.
- Misaligning decimals, which turns 3.6 + 12.45 into 12.81.
- Skipping the estimate and missing an answer that is too big or too small.
How to use this worksheet
Ask students to estimate before they add and to compare the estimate with the answer key.
Common Core connection

- 5.NBT.B.7 · Add, subtract, multiply, and divide decimals to hundredths using place-value reasoning.
A practical match for the skill this worksheet practises, not a claim that one worksheet teaches or assesses the whole standard. Check the official math standards.
For early practice, keep the maximum total small enough that students can focus on the strategy rather than large-number place value. Increase the range only after the addition structure is secure.
Use No regrouping when the lesson is about lining up place values or building fluency before carrying is introduced. Use Require regrouping when every generated problem should include at least one carrying step.
Regrouping (carrying) happens when a column adds to ten or more: in 47 + 38 the ones make 15, so write 5 and carry 1 ten. A common slip is recording the whole column sum instead of carrying, and Require regrouping drills that step.
A fresh seed makes a second form at the same settings. That is useful for reteaching, homework, quick checks, or two practice groups that need the same difficulty without identical answers.

Quick answers
Can I make addition worksheets without regrouping?
Yes. Choose No regrouping and the generator rejects problems that would require carrying in any place-value column.
Which grade level is this for?
Fact fluency within 20 is Grade 1 to 2 (CCSS 1.OA.C.6, 2.OA.B.2). Multi-digit addition with regrouping runs from 2.NBT.B.5 through 4.NBT.B.4.
Can every problem require regrouping?
Yes. Choose Require regrouping and each addition problem is checked so at least one column needs carrying.
Does the addition worksheet include an answer key?
You can include a separate answer-key page when printing or saving as PDF, and you can also reveal answers in the on-screen preview.
