Take your students on a fun-filled learning journey with The MASSive Adventures of Estimating Emma & Measuring Mitch! This engaging worksheet pack allows young learners to develop their understanding of mass through both estimating and measuring using grams and kilograms. Designed for use during a measurement unit, this resource supports students as they explore real-world applications of mass using classroom objects and practical thinking strategies.

With the help of two playful characters, Estimating Emma and Measuring Mitch, students will enjoy building their skills in estimation and accuracy. The characters guide students as they estimate the mass of objects and then check their thinking through hands-on measuring. This format encourages active thinking, comparison, and reflection, while the inclusion of blank templates adds flexibility and student choice.

Whether you are introducing the concept of mass or reviewing key vocabulary and processes, this pack provides a comprehensive and scaffolded way to support your teaching. The worksheets are designed for independent or small group use and can be used across multiple sessions to suit different ability levels.

Key Learning Outcomes:

• ✅ Estimate the mass of objects using prior knowledge and visual clues
• ✅ Measure mass using standard units - grams and kilograms
• ✅ Decide on the most appropriate unit of measurement for different objects
• ✅ Record, compare, and reflect on estimations versus actual measurements

What’s Included:

• 6 differentiated worksheets, each guided by the Emma and Mitch characters:
• - Measuring classroom objects in grams
• - Measuring classroom objects in kilograms
• - Choosing the correct unit for classroom items
• - Three additional blank versions for students to select their own objects to measure

Materials Needed:

• Printed worksheets (A4 or enlarged to A3 if preferred)
• Classroom objects of varied mass
• Balance scales or digital kitchen scales
• Pencils or markers for recording

How to Use:

1. Introduce or review key mass vocabulary, such as grams, kilograms, heavier and lighter.
2. Assign one of the worksheets suited to your lesson focus - either grams, kilograms or mixed measurement.
3. Students estimate the mass of each item, record it, and then weigh the item using a scale.
4. They compare their estimation to the measured mass and reflect on their accuracy.
5. Use the blank templates for students to find and measure their own objects, promoting independence and ownership.

Ideas for Classroom Use:

• 💡 Use as part of a maths rotation focused on measurement
• 💡 Pair with real-life classroom items to make learning more hands-on
• 💡 Use the blank templates for homework tasks involving home-based objects

Top Teacher Tips:

• 💛 Encourage students to use benchmark items (e.g. a glue stick is about 40g) to support more accurate estimates
• 💛 Allow students to discuss their reasoning before weighing to promote mathematical thinking
• 💛 Add a discussion component - which object surprised you the most? Why?

The MASSive Adventures of Estimating Emma & Measuring Mitch is the perfect mix of fun and educational value, encouraging students to actively engage with the concept of mass while building estimation and comparison skills that they will carry into future learning.
