Description
Doubles are one of the first addition strategies a young mathematician can truly own, and this adding doubles worksheet gives first graders the focused practice they need to make those facts automatic. When a child knows that 6 + 6 = 12 without stopping to count, every other addition strategy gets easier: near doubles, making ten, and adding within 20 all lean on the same quick recall. This printable walks through the ten doubles facts from 1 + 1 all the way to 10 + 10, then turns them around so students have to find the missing addend instead of the sum.
Using this adding doubles worksheet takes almost no prep. Print it, hand it out, and let students work down the page. Part A prints each doubles fact as a horizontal number sentence with a roomy answer box, so children write the sum in a space that is easy to see and easy to grade. Part B keeps the same facts but hides one of the two addends, which pushes students to think about what makes a double a double rather than simply adding two numbers that happen to match. An answer key is included on the last page.
What’s Included
- One printable worksheet page plus a full answer key
- Ten doubles facts from 1 + 1 to 10 + 10, printed out of order
- Six missing addend problems built on the same doubles facts
- Large, clearly outlined answer boxes sized for first grade handwriting
- A Name and Date line for easy classroom collection
Three Reasons This Helps Kids
- Doubles facts are the fastest route to fluent addition within 20, and fluency frees up thinking for harder problems.
- Seeing every double in one place helps children notice the pattern that every answer is an even number.
- Flipping to a missing addend builds early algebraic thinking and a real understanding of the equal sign.
Teacher and Parent Ideas
Use this 1st grade addition worksheet as a warm up before a lesson on near doubles, as a quick check after teaching the doubles strategy, or as homework that a parent can score in under a minute. Try reading the facts aloud as a chant first so students hear the rhythm of the doubles before they write them. You can also cover Part B and use it as an exit ticket the following day, or pair students up and have them quiz each other from the completed answer key.
