So, this morning, I am in the same Jr. High as earlier this week. Today I have a math class. Many classes in CPS have “warm ups” at the beginning of class. These are short problems on the subject at hand that get the kids thinking and ready for class. It also occupied the early arrivals while waiting for the stragglers.

This morning, the warm up was: Find the product of 3 2/3 x 2 1/4. Anyway, there is a student teacher in the SMART program, an accelerated Masters program for math and science majors who desire to teach. She worked through the program and got 6 1/6 by multiplying the fraction part to 2/12 and simplifying and then multiplying 3 x 2.

I called her attention to the mistake and still had to prove it to her two different ways before she got it.

And you wonder…
