This is the preview. Hit "Print this worksheet" above to open a clean, ad-free, one-page version with name and date lines and writing space for each problem. A separate answer key prints on the second page for the grown-up. Tear it off before handing the practice page to your child.
Designed for Grade 1 learners, this printable explores Commutative property practice through clear, scaffolded problems that grow in difficulty across the page so kids hit a stretch challenge after the easy warm-up.
Worksheets in this series mix straight computation, short word problems, and visual models so students see the same idea from several angles instead of only one. 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.

We deliberately keep the layout uncluttered: a clean header, generous spacing for kids to show their work, and a problem grid that does not feel overwhelming. Elementary students get tunnel vision on busy pages, and that visual anxiety is often mistaken for a math gap.
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.
Pair this Commutative property practice worksheet with the rest of the Grade 1 Addition within 20 collection for a focused practice block that covers the standard from several angles in a single afternoon.

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.
