A good way to consolidate the formation of the Passé Composé in French. Just write 4 past participles of your choice (I usually do one -ER, one -IR, one -RE and one irregular) in the boxes down the side, and away you go ! Excellent pair game. Each player has a sheet and uses the first grid to record their own ships (we usually have 8) and the second grid to record their hits and misses. Can be adapted for lots of other grammatical points as well.
