I start by saying an animal’s name (e.g. kangaroo). The next child starts their animal with the last letter of my animal (e.g. kangaroO… Octopus).
Everyone must listen really carefully as they cannot repeat an animal. If they do, they are out until they have the chance to put their hand up and fill in for a pupil if they are stuck. Then, when their turn comes around, they are back in the game.
This game could be used with lots of different topics too.
