This printable worksheet gives Grade 4 students focused practice on Mass and weight conversions, an essential building block within Measurement and one of the milestone skills inside the Common Core CCSS.Math.4.MD cluster.
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 get stuck should slow down on the first problem, talk through what the question is actually asking, and only then pick up the pencil. Reading errors disguise themselves as math errors all the time at this age.
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.4.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.
Pair this Mass and weight conversions worksheet with the rest of the Grade 4 Measurement 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.
