One of the ones we did was a gym. We made weights out of empty water bottles, filled with sand or flour or rice. We had a plastic step for step-aerobics, jump ropes, hula hoops, and we put a small rubber mat on the floor to be a treadmill. We also had a table and chairs with fitness and health magazines, and books and puzzles about the body. The children LOVED it!
Another one they seemed to love was a pet shop. Lots of stuffed animals, grooming tools, clothes for the animals, a cash register, and of course a medical kit for the veterinarian. We had plenty of rubber snakes, turtles, and an alligator. We also had some birds among our stuffed toys. We did a zoo one time but that didn't seem to be as popular as the pet shop.
Other fun ones were a pizza shop, a kindergarten classroom, and an office.
