I have been teaching exponents to freshman and sophomores for the last week and a half. I had a carefully planned graphic organizer. I planned on spending 1 or 2 days per exponent property and moving on with the year without too much difficulty... Little did I know what I was up against. Apparently, exponents are not as simple as I had always thought they were. I don't think I really cared in high school why the properties worked. I was great at memorizing things that I needed to know, and so I never had a problem or a need to know, "Why." I was a grade-chaser all the way. Well after teaching every exponent property in the unit and giving a 5-question lesson quiz, I learned that perhaps some of my students had learned nothing over the last week and a half... That's not really true. They had partially learned the properties in isolation, but putting everything together was just too overwhelming. I agree, the students need more practice, but if I had sent them home ...
