I am well aware that today may have been your LAST day of school for the year (thanks Facebook! :) but if you are like me and are still wrapping up before finals, or are already thinking about next year, you can download this reference sheet from the "Freebies" section of the sidebar --->
And if you need an activity for a sub or as a review of simplifying rational expressions, this one here is free and presents adding, multiplying and dividing rationals in terms of area and perimeter. Kids like this one!
Before we started graphing rationals, we simplified them. This flowchart helped kids see that they only needed to find a common denominator when adding or subtracting and only needed to cancel when multiplying and dividing. I'll put a copy of this flowchart in the sidebar too, in case you think it will help your students.
