Start your engines and prepare for a measurement challenge! In this fast-paced digital racing game, students zoom around the track by answering mass estimation questions. With every correct response, their car speeds forward—who will race their way to the winner’s podium first?

Each question presents a familiar object or animal, and students must select the most reasonable estimate of its mass. By evaluating and comparing realistic options, learners develop their understanding of grams and kilograms in a way that feels practical and exciting. Estimating weight becomes a fun and accessible skill as students aim for first place.

Let’s Race – How Much Does It Weigh? is ideal for building fluency and confidence in estimating mass for Years 2–4. Whether used as a warm-up, a maths rotation, or an engaging revision activity, it helps learners link real-world experience to classroom concepts while having a blast.

Key Learning Outcomes:

• ✅ Estimate the mass of common objects and animals
• ✅ Choose appropriate weights using grams and kilograms
• ✅ Strengthen understanding of standard metric units
• ✅ Apply logical reasoning to real-world measurement scenarios
• ✅ Engage in interactive play that reinforces practical maths skills

How to Play:

1. Students are shown a picture or description of an object or animal.
2. They choose the most reasonable mass from three multiple choice options.
3. Each correct answer advances their race car around the track.
4. Incorrect answers leave them in place while others gain ground.
5. The game ends when all questions are answered—and the fastest driver takes the podium!

Ideas for Classroom Use:

• 💡 Use during measurement units on mass estimation and comparison
• 💡 Ideal for Years 2–4 as a fluency task or fast finisher game
• 💡 Pair with real objects for hands-on estimating before or after the game
• 💡 Combine with sorting or weighing activities for deeper understanding

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 estimate and discuss weights with family members

Let’s Race – How Much Does It Weigh? puts estimating mass into top gear, helping students develop practical maths skills while having fun on the track!
