Description

Are your students completing a unit on measuring mass, with a focus on understanding the units of grams and kilograms? The Understanding Mass Worksheet is the perfect way to reinforce these concepts in a practical and accessible format.


This worksheet challenges students to think critically about the most appropriate units for measuring mass. With a combination of written questions and visual prompts, students will learn to distinguish between when it’s more appropriate to use grams or kilograms - building an essential foundation for more advanced measurement tasks.


The engaging format encourages students to consider real-world examples, such as whether you’d weigh a watermelon in grams or kilograms, and why. It’s also a great opportunity to strengthen vocabulary and support students in making meaningful connections to the world around them.


Key Learning Outcomes:

  • ✅ Understand the difference between grams and kilograms
  • ✅ Identify which unit is appropriate for measuring a range of objects
  • ✅ Use measurement language to explain reasoning
  • ✅ Make real-world connections through everyday examples

What’s Included:

  • One-page worksheet featuring:
  • - Multiple-choice and short-answer questions
  • - Visual task to identify correct mass units for common objects
  • - Opportunities for student reflection and justification

Materials Needed:

  • Printed worksheet
  • Pencils or pens for writing responses
  • Optional real-life items from the classroom for hands-on comparison

How to Use:

  1. Begin with a whole-class discussion about when and why we use grams versus kilograms
  2. Introduce the worksheet and review some common classroom items as examples
  3. Have students complete the worksheet independently or in pairs
  4. Encourage discussion and explanation of answers using proper measurement language
  5. Review answers as a class and address any misconceptions

Ideas for Classroom Use:

  • 💡 Include in your measurement unit as an introductory or review activity
  • 💡 Use during small group rotations alongside a balance scale or set of classroom items
  • 💡 Assign as a quick formative assessment to check understanding

Top Teacher Tips:

  • 💛 Display anchor charts that show benchmark items for 100g, 1kg etc. to help visual learners
  • 💛 Reinforce vocabulary like “light,” “heavy,” “grams,” and “kilograms” during your discussions
  • 💛 Pair with a weighing station to support kinaesthetic learners with real measurement experiences

The Understanding Mass Worksheet is a simple yet effective way to introduce or consolidate students’ grasp of mass units. With its relatable examples and mix of visual and written tasks, it’s the perfect fit for any early years or lower primary maths classroom.
