A dismal realization

It’s exam week at IUSB. My vacation will begin on Saturday.

Today, I worked for just two hours. All my appointments with college students were canceled. I only tutored my middle school student. (She’s in the eighth grade.)

Reviewing mathematics with her, I realized that she had no understanding of percentages.

First, she couldn’t tell me what percentage is left over if 15% is subtracted from the whole.

Then, she couldn’t tell me that 15/100 = 15%.

It was one of the most dismaying moments of my tutoring career.
