Use this free Kindergarten math worksheet to help your child master Sums of 10. It belongs to our Addition within 10 collection, aligns with CCSS.Math.K.OA, and is built so a kid with a sharp pencil can finish a meaningful round of practice in roughly ten minutes.
Because the worksheet is designed for independent practice, the directions are written in friendly student language and avoid teacher-only jargon. By the end of the page, learners should be able to explain their strategy in a sentence, not just write an answer.
Print one copy per child, set a quiet 10–15 minute block, and let students work through the page with a pencil and an eraser. Sit with them as they finish so any misconceptions surface right away instead of getting practiced into bad habits.

Parents tell us the most useful thing about this Sums of 10 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.K.OA and supports the broader Addition within 10 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.
If your student finishes this Sums of 10 page quickly and easily, take a look at the next printable in the Addition within 10 series. The difficulty climbs gradually so kids meet a stretch problem without getting overwhelmed.

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.
