This is TOTALLY going to be the year that I teach Related Rates *so* well, that the students will wonder what all the fuss is about its difficulty. Right? At least it keeps me busy picking apart and analyzing what they are struggling with and trying to address all issues.
I started with a flipped lesson just showing applets of related rates. The next class I had planned was walking through these notes:
Then we would do some back and forth translating between words and math expressions. We would also practice implicit differentiation of formulas that now do not involve x and y, but A and r and t and h and the like.
Mother Nature had her say on Friday in Texas, and our school was on Tornado Watch Lockdown and classes were shortened of time. We got through 1/2 this sheet.
But I am keeping my fingers crossed. This. Is. My. Year.
