This year I've revised how I'm going to introduce u substitution to my Calculus kiddos. It's an intimidating topic the first year teaching the course, knowing that it's an area in which students can sometimes struggle. Take 2 and I'm much more ready to let my kids do the directing. I'm using the chart below as a discovery activity for students to being to piece together the pieces (u and du) that will be integral to our future study:
After that, we're doing the following activity to practice identifying useful u's and du's. I know I got this activity from somewhere, but can't for the life of me remember where. If you know where it originated, please let me know!
My kids are taking a quiz next class on basic integration and we'll start u sub as our send off to winter break. Do you have any ways that you love introducing u subs? Any tips or tricks from years of experience I'm in the process of acquiring?
