This activity uses images to help students practice using this (to specify something near) and that (to specify something some distance away). Because students draw the images themselves, they have a greater sense of ownership of the activity. Plus, it's just a bit of (quiet, creative) fun!
Trying to create a realistic scenario students can act out where they might naturally use the grammar "I mean the man reading a newspaper." isn't so easy. Instead of trying to force it, I decided we should write a poem instead.
The man trying to look busy.
The ladies sharing gossip in huddles of office chairs.
The computers shedding heat into the stuffy room.
