I guess I've been kinda into flow charts this year; I created another one for solving exponential and log equations. The idea is that kids start with the top box, if they can't complete that task, then they go on to the next box. We put examples in each box. I used this for both Algebra II and Pre-Calc this year.
It's not flawless, because mathematics requires more creativity than a flow chart can provide. But it gets the basic ideas across.
