One side of the paper is the drawing areas, the other the lines for text.
Instruct students to listen carefully to your key words. They have 30 seconds to draw your key word as many times as possible in the appropriate box.
I chose simple things like socks, bananas etc to start with, then threw it some hard ones like Kappa Sushi Hello Kitty Grape Juice, 2005 Nissan Cube etc. near the end.
After drawing, get them to flip over the sheets, make pairs, and ask each other "How many _______ did you draw?" Armed with that information, they write two sentences. One in the past as "I drew six buses", and one as the past passive "Seven buses were drawn by Tomoya."
Here's the sheet.
Expect to fill around 15 minutes.
