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.
Bring focused, low-prep practice into your classroom or home with this Kindergarten worksheet on Comparing weight (heavier/lighter). It targets the Measurement strand of the Common Core math standards (CCSS.Math.K.MD) and prints cleanly on a single sheet of letter or A4 paper.
Because the worksheet is designed for independent practice, the directions are written in friendly student language and avoid teacher-only jargon. 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.
Strong students can race the clock and aim for a personal best. Students who need more support can work in pairs and explain their thinking out loud, which is one of the highest-leverage moves in elementary math because it forces students to put fuzzy thinking into clear words.

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.K.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 Comparing weight (heavier/lighter) 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.
