Hello everybody! Actually this worksheet was made for the Challenges textbook for teens, but perhaps it can be used everywhere as additional material. So, the procedure is the following=) 1. Cut up cards (in the paper there are 2 charts for two pairs of children); 2. Organize kids into groups of three or four; 3. One student reads the card without a preposition (usually we substitute it by- balh blah blah=) ) 4. The rest of the group should guess the correct preposition. Who was the first - keeps the card. 5. The student with the most cards in the end is the winner! Have fun!
