Free Addition Worksheets
Column-free addition practice from single digits to three-digit sums, with and without regrouping. Every worksheet has 20 problems and an answer key; press “New worksheet” for a fresh set.
How these worksheets work
Choose a level below. Each worksheet has new numbers every time you ask for one, so you can print as many different sheets as you need. Answers are worked out by the generator and printed on a separate page.
Start at the first level and move on when a sheet can be finished quickly with few mistakes. Short, regular practice (one sheet a day) builds fluency faster than long sessions, and timing a sheet now and then shows progress clearly.
Levels
Choosing the right level
- Single-digit addition (0–9), usually kindergarten and grade 1. Typical problems: 0 + 3 = 3; 2 + 8 = 10; 5 + 7 = 12.
- Two-digit, no carrying, usually grade 1. Typical problems: 10 + 11 = 21; 60 + 25 = 85; 73 + 11 = 84.
- Two-digit, with carrying, usually grade 2. Typical problems: 65 + 16 = 81; 23 + 19 = 42; 52 + 71 = 123.
- Three-digit addition, usually grades 2 and 3. Typical problems: 517 + 744 = 1261; 912 + 618 = 1530; 834 + 689 = 1523.
If a child gets more than a few problems wrong on a level, stay there for another sheet or two. If a sheet is finished quickly and almost all correct, move to the next level. Each level page has its own answer key and a button for a fresh set of numbers.
Worked example: 10 + 11
This problem comes from the two-digit, no carrying level. The method is the same for every problem on that sheet:
- Ones column: 0 + 1 = 1. Write 1.
- Tens column: 1 + 1 = 2. Write 2.
- Read the digits from left to right: the answer is 21.
Printing and reuse
Every level prints on plain paper with the answers on a separate page. Because the numbers change each time you press “New worksheet”, you can give a different sheet to each child or repeat a level many times without anyone memorising the answers.
The sample problems above are taken from the same generators as the printable sheets, so they show exactly the kind of numbers each level uses.
Teaching tips
- Line the numbers up by place value before adding: ones under ones, tens under tens.
- Always start with the ones column and move left, so carried digits land in the right place.
- Estimate first by rounding to the nearest ten. If the answer is far from the estimate, look for a missed carry.
- Once a sheet is easy, time it and try to beat the time on the next one rather than moving up a level straight away.
