Giant robots are attacking and only your maths skills can save the town! In this exciting digital game, students work together to defend a town under siege. Each correct answer earns upgrade points that can be used to grow the population, build stronger walls, or attack the invading robots.

This version of the game challenges students to explore number patterns involving doubling, halving, and multiples of 2, 5, and 10. As they respond to a mix of pattern-based and practical questions, they’ll build fluency, identify sequences, and apply strategies for reasoning with numbers.

Let’s Defend – Doubling & Halving Number Patterns is a cooperative adventure where teamwork and thinking skills go hand in hand. With each question answered correctly, students strengthen the town’s defences, and with every incorrect answer, the robots creep closer. The goal? Keep the town safe and make it stronger than ever!

Key Learning Outcomes:

• ✅ Recognise and extend number patterns involving doubling and halving
• ✅ Identify and continue patterns involving multiples of 2, 5 and 10
• ✅ Strengthen mental computation and pattern reasoning
• ✅ Develop fluency with skip counting and number sequences
• ✅ Engage in team-based, interactive number play

How to Play:

1. Students answer questions involving number patterns and multiples.
2. Correct answers earn points that can be used to upgrade and defend the town.
3. Players choose whether to build homes, fortify defences, or attack the robots.
4. Incorrect answers allow the robots to damage the town’s structures.
5. The team wins by surviving all rounds with the strongest town possible.

Ideas for Classroom Use:

• 💡 Use during number pattern units to consolidate fluency with doubles, halves, and multiples.
• 💡 Great for Years 3–4 working on early number sense and skip counting.
• 💡 Add to maths rotations for team-based reasoning tasks with real-time feedback.
• 💡 Extend learning with follow-up tasks like “build your own pattern” challenges or number sentence writing.

Top Teacher Tips:

• 💛 Send the QR code home for students to play as a homework or revision task.
• 💛 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.

Let’s Defend – Doubling & Halving Number Patterns turns number sense into a high-stakes mission where teamwork, strategy, and maths save the day!
