Bring focused, low-prep practice into your classroom or home with this Grade 1 worksheet on Doubles facts. It targets the Addition within 20 strand of the Common Core math standards (CCSS.Math.1.OA) and prints cleanly on a single sheet of letter or A4 paper.
Each printable is a single black-and-white page that prints cleanly on standard letter or A4 paper, so teachers and parents can run off a class set or a single copy without wasting toner. Students who finish quickly can flip the page over and write two new problems of their own that target the same skill. It's a powerful retention trick that doubles as a quick formative check.
This page works well as morning math, as a center rotation, as a short homework assignment, or as a quick formative check before a quiz. The same one-page format also makes it easy to keep a small folder of completed work as evidence for parent–teacher conferences.

Parents tell us the most useful thing about this Doubles facts page is how fast they can hand it to a kid. No login. No PDF locked behind an email gate. Click print, hand it over, get ten quiet minutes of real math practice without prepping anything.
This worksheet is aligned to Common Core State Standard CCSS.Math.1.OA and supports the broader Addition within 20 progression that students continue to build through later grades. The same skill is revisited each year with greater abstraction, so the work your student does on this single sheet feeds into the multi-digit and multi-step problems they will see in middle school.

How to use this worksheet
Print one copy per child on standard letter or A4 paper. Set a quiet 10 to 15 minute window. Hand your student a sharpened pencil and an eraser, and let them work top to bottom. The first row is a warm-up on purpose. The last row is a stretch on purpose. Sit with them as they finish so any misconceptions surface right away instead of getting practiced into a bad habit.
If your student finishes quickly, flip the page over and ask them to write two new problems of their own that target the same skill. It's a powerful retention move. If they get stuck, pull out manipulatives that match the skill (counters for early addition, base-ten blocks for place value, fraction tiles for fractions) and work through one or two problems together before letting them try the rest on their own.
