Who doesn’t love paper aeroplanes? I mean apart from the person who has to tidy them up?
I took different sets of instructions from www.paperaeroplanes.com and told my students to practice making the plane. I made sure to tell everyone they would be teaching how to make their plane later.
The vocabulary needed was in the reading but be aware that inattentive students may ignore it. I would have them read and copy out a list of ten or so useful vocabulary items if I did this again. Focus on form was given as we went.
There was the opportunity to ask meanings of words as we went along and the instruction task was passed if planes were made and failed if they didn’t.
Plane types were tested for speed, height and distance. Students then wrote up a short report.
As extension work, we tried folds to the wings and fuselage to see if the planes would turn or roll.
The students loved doing this and everyone was speaking English all the time. There was even more negotiation of meaning than usual, too.
