Divide the students in two teams. Write on the board words that pupils already know. Give to each team the following two cards;
On the first card write “Yes!” and on the second write “No!” Each team takes turns in spelling the words. Whenever a team spells the words correctly, the other team raises the first card and the team gets 2 points. However, whenever a team doesn't spell the words correctly, loses 2 points and the other team raises the second card. The team with the most points earns 3 stickers!
