This month, try this idea as a starter with your classes.
Give each pupil a piece of paper and tell them to divide it into 8 strips (folding it 3 times works best). They then write a word or phrase into each section (target language or English) from the last topic. The idea is that you say the phrases in the opposite language. If they have that phrase at either the top or the bottom of their piece of paper, they may tear it off. They obviously may not tear off the strip if it's in the middle of the piece of paper.
The winner is the person who is able to tear the last piece in half.
