Support your students as they explore mass through hands-on, real-world investigations with our engaging Formal Mass Scavenger Hunt: Gram & Kilogram Worksheets. This fun and practical activity helps students develop a strong understanding of formal mass measurements by encouraging them to identify items in the classroom that correspond with specific gram and kilogram values.

Each worksheet lists a series of masses for students to match with real classroom objects. From pencil cases to glue sticks, students are challenged to use scales and estimation strategies to identify items that closely align with the target weights. This inquiry-based task promotes deeper understanding of metric units and reinforces the concept of relative mass in an engaging, student-led format.

Three differentiated versions of the worksheet are provided to support varying levels of ability and confidence. The first version focuses on six simple measurements in grams. The second expands to eight items, incorporating both gram and kilogram values. The final worksheet includes ten measurements and offers a broader range of mass values using both grams and kilograms, allowing for a more complex comparison task.

Key Learning Outcomes:

• ✅ Recognise and apply formal units of mass (grams and kilograms)
• ✅ Estimate and compare the mass of everyday classroom items
• ✅ Use measuring tools such as scales to record accurate measurements
• ✅ Develop reasoning skills when matching objects to given values
• ✅ Engage in a student-led, inquiry-based measurement task

What’s Included:

• Three differentiated worksheet versions:
  • - Version 1: Six mass values in grams only
  • - Version 2: Eight mass values using grams and kilograms
  • - Version 3: Ten mass values with greater variety in grams and kilograms
• Clear and student-friendly layout to support independent use
• Space to list corresponding classroom items for each mass
• Answer sheet provided for reference and class discussion

Materials Needed:

• Printed copies of the worksheet (Version 1, 2 or 3)
• Classroom objects of varying mass (pencil cases, books, water bottles, etc.)
• Digital or manual kitchen or school scales for weighing items
• Pencils or markers for recording responses
• Optional: clipboards for students to carry around the room

How to Use:

1. Introduce the concept of formal mass units and revise key vocabulary (grams, kilograms, heavier, lighter).
2. Assign a worksheet version based on your students’ confidence and ability level.
3. Invite students to move around the classroom in search of objects that match the listed masses.
4. Have students estimate each item’s mass first, then confirm using a scale where appropriate.
5. Encourage students to write down the name of the object that most closely matches the given mass value.
6. Conclude with a discussion to compare findings and reflect on the accuracy of estimations versus measurements.

Ideas for Classroom Use:

• 💡 Use as part of a hands-on Maths rotation or STEM session
• 💡 Introduce at the beginning of a unit on formal measurement
• 💡 Extend by challenging students to create their own mass scavenger hunt for peers
• 💡 Pair with informal mass activities to support comparison between measurement types
• 💡 Use laminated copies with whiteboard markers for repeated use over several sessions

Top Teacher Tips:

• 💛 Pre-weigh a selection of classroom items and label them discreetly to support early finishers or less confident students
• 💛 Set up weighing stations to reduce crowding around scales
• 💛 Use clipboards and partner work to encourage collaboration and discussion
• 💛 Store the resource alongside a set of common measuring tools for easy access during future lessons

Formal Mass Scavenger Hunt: Gram & Kilogram Worksheets is the perfect way to bring measurement to life in your classroom. With scaffolded levels, hands-on exploration and practical application of skills, this resource helps students connect Maths to their everyday world while building essential measuring knowledge.
