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.

Use this free Grade 3 math worksheet to help your child master Mass with grams and kilograms. It belongs to our Measurement collection, aligns with CCSS.Math.3.MD, and is built so a kid with a sharp pencil can finish a meaningful round of practice in roughly ten minutes.

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.

Teachers tell us the most useful thing about this Mass with grams and kilograms page is that it can be dropped into morning math, into a small-group rotation, or into a homework folder without any pre-teaching. Students can read the directions, look at the first warm-up, and start working without waiting for a grown-up to translate.

This worksheet is aligned to Common Core State Standard CCSS.Math.3.MD and supports the broader Measurement 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 Mass with grams and kilograms page quickly and easily, take a look at the next printable in the Measurement 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.

Common Core alignment

This page targets CCSS.Math.3.MD inside the broader Measurement progression. The skill is introduced earlier in elementary school through concrete representations and revisited each year with greater abstraction.
