A word flashes up in the middle: is it a noun, a verb or an adjective? Both teams race to sort it. First correct answer takes the point, but a wrong tap locks you out and gives the other team all the time they need. First to 10 points wins the showdown.
Built for an interactive whiteboard or a shared tablet: one player (or team captain) stands at each side. Naming word classes quickly is core SATs grammar, and the lock-out rule rewards children who check ("could I put THE in front of it?") before they tap. Every word was picked so one class clearly fits best.
