At the beginning of class, I went over each of the types of transformations that we’ve done throughout the chapter. I wrote each one on the board and wrote down what and with what we’d have to replace a variable with to translate, reflect, or vertically stretch a graph.
With the second class, I began by doing question number 1 with them since it was difficult. About a third of the class period finished the work which they had about 30 or 35 minutes to do it in.
The biggest problem that I see is that students will try to write the answer with no work shown despite me showing them all the steps on the board over and over. For instance, I’ll write down something like this:
Then there is the problem with order of operations – I’ve been making sure that when there is more than one transformation that I’m asking the students which (if any) must come first. This is easier to do with Sketchpad open.
