Substitute Teacher Idea - How Many

I'm having a substitute teacher in the class tomorrow while I take a day off to for a doctor's appointment. And while trying to figure out something for the kiddos to do, I came up with this idea.

Each child gets a half-sheet. (You can click on the jpg picture above to get a full-sized version you can save and print.). Before I ran off the copies, in the big rectangles I wrote such items such as TV, CHAIRS, TABLES, FLAGS, COMPUTERS, etc. The smaller rectangles on the right are for the kids to write the quantities. 

It's rather like a combination scavenger hunt and inventory game. I'm hoping they get a kick out of it. Plus I can keep a master to make other similar "hunt and count" activities.
