This entry is off the topic of flipping, but something I want to sort out for myself by writing. It's about Fractions.
I plan to teach an intro to grade 7 course for kids entering high school, and they come in with minimal to no skills in working with fractions. My goal is to come up with activities/examples/applications to make 'em accept that fractions MUST be included and understood in grade 7 math.
Starting with something they understand or should understand... Test results. Given a quiz: 11/20, test: 33/42 or homework: 8/10, how do we compare the results? Well you don't need fractions, you just have to change to percentage... WHICH IS SILL A FRACTION, JUST THAT IT's out of 100. Lots of fraction work there, and estimation skills. But what if you wanted to do it without fractions?
That's a stat... Then maybe a couple of historical questions, and tools for matching things up for comparing skills. Addition and Subtraction would fall out of there, but maybe I should do multiplication first. What fraction of the day is left for Mr. Powell to sleep if he burns the candles at both ends?
And then again, this may be perfect for a flipped lesson.
