This activity can work in a number of ways to help your students revise prepositions and conjunctions. 44 cards (or trucks) depicting prepositions and conjunctions. Two trains displaying preposition or conjunction signs. Train designs are also blank if you don’t wish to specify. Train ‘smoke’ cards. You can print as many of these as required. Version 1: Train not specified. Students can connect all the trucks and place the correct ‘smoke’ sign above each truck. You’ll need to print as many smoke signs as necessary. Version 2: Students must sort through all the truck cards and build the ‘Preposition Express’ or the ‘Conjunction Express’. This can be a fun, timed group activity with as many sets of the game as required.
