Get ready for a hands-on, fast-paced way to practise converting between millimetres, centimetres and metres with Length Mastery – a measurement board game that brings length conversions to life! This engaging and interactive game is perfect for small groups and helps reinforce students’ understanding of length as they move through the gameboard solving real-world measurement problems.

In this game, students will encounter a variety of measurement values that must be converted from one unit to another. Whether they’re changing 2.4 metres into centimetres or converting 670 millimetres into metres, students will be challenged to apply their knowledge of metric units in a meaningful context. This not only deepens their understanding but also builds confidence and fluency with metric conversions.

With enough game boards for up to six players, this resource is ideal for small group rotations, maths stations, or targeted intervention work. The competitive and cooperative elements of the game encourage discussion and peer learning, while the built-in repetition supports mastery. Use the game regularly to review skills or as a way to challenge students who are ready for deeper measurement tasks.

Key Learning Outcomes

• ✅ Convert between millimetres, centimetres and metres
• ✅ Practise mental strategies and written methods for measurement conversion
• ✅ Apply knowledge of metric units to real-world length problems
• ✅ Develop confidence working with all three common length units

What’s Included

• 6 full-colour game boards – one for each player
• Measurement conversion cards featuring millimetres, centimetres and metres
• Answer key for teacher or peer checking
• Instructions for setup and play

Materials Needed

• Printed game boards (preferably on thick card for durability)
• Game tokens or small counters – one per player
• Printed and cut conversion cards
• Optional: dice, write-and-wipe sleeves or plastic sleeves for reusability

How to Use

1. Print out the game boards and conversion cards. Laminate for reuse if desired.
2. Give each student a game board and a token to move around the board.
3. Students take turns drawing a conversion card and answering the problem aloud or on paper.
4. If correct, they move forward the indicated number of spaces; if incorrect, they stay put.
5. Continue until all students reach the finish or the time limit ends.

Ideas for Classroom Use

• 💡 Use in Maths rotations as a measurement review station
• 💡 Play in pairs to encourage discussion and peer teaching
• 💡 Run a class-wide ‘Measurement Championship’ with rounds played over a week
• 💡 Introduce before a formal test or assessment on metric conversion

Top Teacher Tips

• 💛 Differentiate by removing or simplifying the more challenging conversions for early learners
• 💛 Print game boards in A3 size for group play or classroom display
• 💛 Store each set in a zip-lock bag with the cards and counters for easy grab-and-go access
• 💛 Laminate all components and use dry-erase markers for quick, reusable maths stations
