It was time to line up at the end of class and the kids were sitting on the center circle. I told them that if they thought the activity we did in class that day was "aerobic" they could line up. Some kids jumped right in line and others weren't sure and I see a hand up in the center of the line. I called on the student and he said, if "aerobic" means "not fun" can I go sit back down. I had a great time today!
