Description

Race around the track in this fast-paced mental maths game. With each correct answer, your car zooms ahead - bringing you closer to the winner’s podium. Will your maths skills be enough to take the lead and claim the top spot?


This version focuses on three-digit addition and subtraction. Students use partitioning, rearranging, and regrouping strategies to solve each equation. Whether breaking numbers into hundreds, tens and ones or using friendly number strategies, students build fluency as they accelerate toward the finish line.


Speed matters - but so does accuracy! The more correct answers you get, the faster your car travels. Incorrect answers will slow you down, so strategy and precision are key.
