Classroom sweeps are a fun way to practise minimal pairs, or any other activity where there’s a choice of two answers.  Having decided what minimal pairs you’ll be focusing on, for example /ɪ/ and /i:/, get the students to stand in the middle of the room.  Explain that they must run to the left wall if they hear a word with the /ɪ/ sound and to the right if they hear the /i:/ sound.

You can also do classroom sweeps with more than two options – just be careful where you’re standing or you might get knocked over in the rush!
