Divide the students in two teams. Print and cut out planets from cardboard. Also print and cut out spaceships from cardboard. Stick on each planet and on each spaceship a letter from the alphabet. Make sure that each spaceship matches a planet. Spread them all over the floor and shout out “Blast off!” Each team has at their disposal 10 minutes to match all the spaceships with the correct planets. For each spaceship that students match with the correct planet, their team gets 1 point. The team with most points earns 2 stickers at the end of the game whereas the other team takes only 1.
