Free Addition Math Worksheets – Sum up to 20

Two Big Sets of Addition Worksheets Up to 20 (200 Pages to Print and Use!)

If you’ve been looking for easy, ready-to-print addition worksheets up to 20, you’re going to love this. I put together two full sets, each with 100 unique pages, all focused on simple addition practice. Both sets follow the exact same layout – they just have different randomly generated problems so you get more variety without repeating pages.

That means you get 200 total worksheets you can print whenever you need a quick math activity.

These sheets are perfect for teachers, homeschoolers, parents, and tutors who want something clean, simple, and no-prep.


Why Addition Up to 20 Is Important

Before kids can move on to bigger math topics like double-digit addition or subtraction strategies, they need to feel comfortable with basic addition facts. Practicing sums within 20 helps kids:

  • Build confidence
  • Increase speed and accuracy
  • Strengthen number sense
  • Prepare for more advanced math

Even doing one sheet a day can make a huge difference over time.


What’s Inside Each Set

Both Set 1 and Set 2 include the same style of worksheets:

100 printable pages per set

Every page has 10 addition problems, all with answers that stay within 20.

Name and date fields

Helpful for keeping track of daily work.

Score box

Easy way to see progress or check how many answers were correct.

Clean, simple layout

Nothing distracting – just straightforward math practice.

The only difference between the two sets is that they contain different randomized problems. So Set 2 gives you another 100 pages that look the same but offer brand-new sums.


Who These Worksheets Are Great For

Teachers

These sheets work well for morning work, quick practice, review, early finishers, or homework. With 200 total pages, you’ll always have something ready to use.

They make daily math simple. No prep, no complicated instructions—just print and go.

Parents

Simple Ways to Use the Worksheets

  • Print one page per day for steady progress
  • Use them as quick practice before starting a lesson
  • Keep a stack ready for days when you need an easy filler activity
  • Track scores over time to see improvement

Nothing fancy – just simple, consistent math practice that works.


Why Having 200 Worksheets Helps

You get a huge variety of pages, which means:

  • Kids don’t get bored seeing the same problems
  • You don’t have to search for new printables every week
  • You can build a full routine around daily practice
  • There’s enough material to last an entire school year and beyond

It’s one of the easiest ways to build strong addition skills without adding extra work for yourself.
