Addition Worksheets for Kindergarten & 1st Grade

Free addition worksheets for every level

Addition is the first big step in math after counting. A child learns that putting two groups together makes a bigger group, and later learns to do it in their head. This generator makes printable addition worksheets in seconds. Choose how high the numbers go, pick a layout, and press Print or Save as PDF. Every page can come with an answer key.

What to practice at each level

Many U.S. schools follow standards that build addition up in small steps. The table below is a guide only, so always follow your child’s own pace and your teacher’s plan.

Choose a worksheet type

• Vertical (stacked): the numbers are written one under the other, the way children add in school. It is the best layout for two-digit addition.
• Horizontal: problems such as 6 + 3 = ___, written side by side. It is good for learning addition facts.
• Missing number: problems such as 4 + ___ = 9. Your child works backward, which builds a deeper understanding of how numbers fit together.
• With pictures: two groups of pictures are shown, and your child counts them and adds. Pictures are ideal for preschool and kindergarten.

How to use the generator

1. Choose Addition as the operation, or Mixed for addition and subtraction on one page.
2. Choose a worksheet type and how high the numbers go.
3. For numbers within 100, decide whether to allow carrying (also called regrouping).
4. Choose how many problems you want and check the preview.
5. Press Print or Save as PDF. Turn on the answer key page if you need one.

Tips for learning addition

• Start with objects. Add with blocks, snacks or toys before moving to paper.
• Count on. To add 3 + 5, start at 5 and count up three more: 6, 7, 8.
• Learn the doubles. Facts such as 4 + 4 and 6 + 6 are easy to remember and help with the facts next to them.
• Make a ten. To add 9 + 6, think 9 + 1 + 5. Making a ten is a strong strategy for sums within 20.
• Keep it short. Ten minutes a day works better than one long session, and fingers are allowed.
