Hey, how do I download it?
This is a warmer, and there is nothing to download. It's just an idea for your lesson, not a worksheet.
Ask students to name as many objects in the classroom as they can while you write them on the board.
This can be made slightly :) more competitive by splitting Ss into teams and giving them a 5-min time limit (in which case they'll need to brainstorm those words and put them on a piece of paper, not the board).
