Plural tennis

1. The teacher explains that the students are going to play tennis with words, counting from 1 to 30 and using plurals as tennis balls. The teacher splits the class into to teams, who turn to face each other. The teacher gives a letter, which will be the initial letter of the first words in the game. The students count in turn, 1 student from each team alternately, using a plural noun which begins with the letter given. This can only be changed when someone gives a word that rhymes with the previous one – then the initial letter of the rhyming word must be used,
e.g. Team A Team B
One boy. Two bottles.
Three buildings. Four bombs.
Five bridges. Six fridges.
Seven foxes.
2. Mistakes or repetitions of a noun count as penalty points against the team. The teams score 1 point when they use the rhyme to change the letter, and also when they use an irregular plural (for example children, thieves, etc)
