This lesson teaches students to ask a favour through the use of the expression "I was wondering if I could..."
This post consists of the following:
1. A prezi with the target expressions and a dialogue
http://prezi.com/gb3yoifrlvaf/asking-a-favor/2. A worksheet for the main activity. The worksheet functions as a kind of BINGO - students need to convert the sentences in each block to start with "I was wondering if I could ..." I divided the class in half and got each side to cross off as many blocks in the BINGO as they could in a 2 minute time-frame.
Please adapt according to your needs...
