Two players race: is the word in bold a noun, a verb or an adjective? First correct answer takes the point. First to 10 wins.
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 because a wrong answer locks that team out for the word, children learn to check ("could I put THE in front of it?") before they tap. Every word was picked so one class clearly fits best.
