Explore outer space and collect different objects to earn space badges as you warp between galaxies with every correct answer. As students journey through the stars, they’ll strengthen their understanding of measurement concepts in a fun, interactive way!

In this version, students compare two objects and decide which one is heavier or lighter. This activity builds early measurement vocabulary and reasoning skills while helping students develop an understanding of mass in everyday contexts.

Let’s Explore – Mass: Heavier or Lighter? is perfect for Foundation and Year 1 students learning to compare objects using informal language. It’s a great addition to your measurement unit, independent practise time, or maths rotations using the QR code for easy access.

Key Learning Outcomes:

• ✅ Compare two objects and determine which is heavier or lighter
• ✅ Use appropriate language of measurement to describe mass
• ✅ Develop observation and reasoning skills
• ✅ Strengthen understanding of comparative mass in real-life contexts
• ✅ Engage with measurement concepts through interactive, space-themed gameplay

How to Play:

1. Students are shown two objects side by side.
2. They choose which object is heavier or lighter based on visual comparison.
3. Each correct answer earns a space object and warps them to the next galaxy.
4. Collected objects contribute to the final badge tally.
5. At the end, students are shown all the space badges they earned throughout their journey.

Ideas for Classroom Use:

• 💡 Use during Foundation and Year 1 measurement units focused on mass comparison
• 💡 Great for building vocabulary like heavier, lighter, more than, and less than
• 💡 Pair with hands-on classroom activities using real objects for mass sorting
• 💡 Add to independent practise rotations to build fluency and confidence

Top Teacher Tips:

• 💛 Let students personalise their experience by choosing from six characters before the game begins
• 💛 Select the number of players or teams at the start of the game to suit individual, paired, or group play
• 💛 Send the QR code home for students to play as a homework or revision task

Let’s Explore – Mass: Heavier or Lighter? helps young learners compare, reason, and describe the world around them—through an exciting space-themed adventure!
