Yesterday, in our opening discussion on fractions, I asked the kids to count all of the students in the room. Lots of sweeping glances and finger pointing around the room as the kids counted.
I then asked them what fraction of kids in the room were boys. Again, a flurry of exaggerated counting, with mostly right answers shouted out. Finally, I asked them what fraction of kids in the room were girls. Same activity of spinning in chairs to count everyone one by one.
When that was done, I told the kids that I knew what the fraction of girls was without even needing to actually COUNT the girls in the room. The TA in the room with me at the time spoke up with a "Me too!"
I asked the kids to discuss with one another how it was that Mr. Ball and I knew the fraction without needing to count.
Several kids immediately shouted out, "BECAUSE YOU'RE SMART!!!"
Well, sure, but not exactly the answer I was looking for...
