After introducing the key preposition lesson you may find it useful for some students to have the opportunity to have concrete, hands on experiences to reinforce the concept.
I have created some easy to prepare preposition extensions cards for such occasions. These cards are used in conjunction with items you would find in your classroom (if not they would be easy enough to find at home!).
There are five sets of six cards. Each set has a small graphic in the bottom corner to help keep the sets organised easily
