A times-tables penalty shootout for two players or two teams on one screen. Each side races through their own questions: every correct answer kicks the ball towards the other team's goal. Answer faster than your rivals and the goals fly in! Two minutes on the clock.
Built for an interactive whiteboard or a shared tablet: one player (or team captain) stands at each side of the screen. Speed of recall is the skill being trained, and a touch of friendly competition gets far more answers per minute out of children than a worksheet ever will. Swap players between matches so everyone gets a turn.
