Work together to build and protect a town that is under attack by giant robots. Choose to upgrade the homes within the town and grow the population, strengthen the town walls or actively attack the robots.

Decimal Multiplication & Division Let’s Defend challenges students to apply their understanding of multiplying and dividing decimals by multiples of 10. As they work through each problem, students use estimation and rounding strategies to check the reasonableness of their answers while helping their team defend the town from danger.

With every correct answer, players choose how to strengthen their town – grow the population, reinforce the walls, or launch an attack on the invading robots. It’s a cooperative, strategic game that combines high-level maths thinking with teamwork and decision-making.
