This cartoon reminded me (Cathy) of an incident from when I was teaching grade four. The math problem for the day was:
A man went to bed at 11:00 p.m. and got up at 7:00 a.m. the next day. How many hours did the man sleep?
One of my students just couldn’t figure it out it. He usually didn’t have problems with mathematics, but he just couldn’t “see it”. In an effort to guide him, I told him to draw a clock and count the hours in between 11 and 7.
Sometime later I noticed he was sitting at his desk just staring at his notebook. I walked over to see what he was staring at. This is what he had drawn:
I guess my technology wasn’t matching up with his technology. It’s a constant challenge!
