Free doubles addition worksheets
Free doubles addition worksheets with answer keys. Practice doubles facts like 3+3, 7+7, and near doubles — printable PDFs for grades K-2 math.
Doubles facts — 1+1, 2+2, 3+3, all the way to 10+10 — are some of the easiest addition facts for kids to remember, and they unlock a powerful strategy for solving nearby problems. If a student knows 6+6=12, they can quickly figure out 6+7=13 (just one more) and 6+5=11 (just one less). These worksheets build fluency with doubles and then extend to "near doubles" and "doubles plus one" strategies.
What Students Will Practice
- Memorizing all doubles facts from 1+1=2 through 10+10=20
- Using visual models (matching groups, dominoes, ten frames) to understand why doubles work
- Applying the "doubles plus one" strategy: if 7+7=14, then 7+8=15 (one more than the double)
- Applying the "doubles minus one" strategy: if 8+8=16, then 8+7=15 (one less than the double)
- Connecting doubles to real-world scenarios (two hands with 5 fingers each = 5+5=10, a dozen eggs split evenly = 6+6=12)
- Building speed and automaticity through targeted doubles drills
Doubles facts are typically taught in kindergarten through 2nd grade as a key mental math strategy. They provide anchor facts that make learning the rest of the addition table much faster.

How to Use These Worksheets
Doubles are the anchor facts of addition — invest time in making them automatic.
- Use visual models first: show two groups of 4 blocks, count both groups (4+4=8). The visual symmetry of doubles makes them naturally memorable. Dominoes are perfect for doubles practice because each half shows the same number of dots.
- Practice doubles facts separately from other addition facts. Because they follow a clear pattern and are easily visualized, most students can memorize all 10 doubles facts in just a few days of focused practice. This quick success builds confidence.
- Once doubles are solid, introduce the "doubles plus one" strategy explicitly. Write 6+7 on paper. Say: "6+6 is 12 — that's our double. 6+7 is just one more than 6+6, so it's 13." Practice this thinking aloud with multiple examples until the strategy feels natural.
- Use the timed drill pages to test speed. Doubles facts should be answered in under 2 seconds — faster than other addition facts because they're so frequently used and so pattern-based. Track your child's time improving over days to show progress.
Common Mistakes to Watch For
- Confusing near-doubles direction: For 6+7, students should think "6+6=12, plus 1 more = 13." Some students subtract instead: "7+7=14, minus... wait..." The simplest approach is always: double the smaller number, then add 1. This avoids confusion about which direction to adjust.
- Not recognizing when to use the strategy: A student might know the doubles strategy on a worksheet labeled "Doubles" but not apply it when they see 8+9 on a mixed practice sheet. Point out near-doubles whenever they appear: "Hey, 8+9 — is that close to a double?"
- Memorizing doubles but not understanding them: A child might know 7+7=14 by rote but not understand why. Use concrete examples: "If you have 7 crayons and your friend has 7 crayons, how many together?" Understanding prevents the fact from being lost if memorization fades.
- Only learning doubles up to 5+5: Students sometimes have solid doubles for small numbers (2+2, 3+3, 4+4) but haven't practiced the larger ones (8+8=16, 9+9=18). All doubles through 10+10 should be automatic, since the near-doubles strategy is most useful for the harder addition facts.
Frequently Asked Questions
Why are doubles facts taught as a separate strategy?
Doubles facts are uniquely easy to remember because of their visual symmetry and pattern (even sums). Once memorized, they become anchor points for the entire addition table through the near-doubles strategy. A student who knows all 10 doubles facts can derive roughly 20 additional facts from them. That's significant efficiency.
When should my child know all doubles facts?
Most students can memorize doubles facts by the end of kindergarten or early 1st grade. The near-doubles strategy (doubles plus or minus one) is typically practiced in 1st-2nd grade. Since there are only 10 facts to learn, focused practice over 1-2 weeks is usually enough for mastery.
How do doubles connect to multiplication later?
Doubles ARE multiplication by 2. When your child says 6+6=12, they're also learning that 2x6=12. This connection becomes explicit in 2nd-3rd grade when multiplication is introduced. Students with strong doubles facts transition to the 2 times table with almost no additional learning needed.
My child already knows basic addition. Are doubles worksheets still useful?
Yes, if the near-doubles strategy is included. Even students with solid addition skills benefit from making the strategy explicit. And practicing doubles to full automaticity (instant recall) makes all subsequent addition faster, which matters for timed tests and multi-step problems.
After mastering doubles and near-doubles, students have a powerful strategy toolkit for addition. Combined with "making tens" and counting on, these strategies cover virtually every single-digit addition fact efficiently.
