Review the prepositions students learned in the last class. Present a poster of prepositions, and introduce the pattern. Information Gap: divide students into pairs, and ask them to fill the different worksheets by the information which the other one offers. Oral Practice & Worksheet writing: Ask individual student to do one-on-one oral practice with the teacher. The others should do the pattern exercise on the worksheets while the specific student is doing one-on-one oral training.
