2 pages. Print the first one on coloured paper and the next page on a different colour. Cut out the flashcards. Flashcards are now ready to use. Put students in groups and get them to match the numbers and words. Play a matching game: turn cards word down, the first student of the pair must turn over one card of each colour and say the corresponding word. If they turn over a pair with the same meaning (2 and two) they keep the cards and get one point.
