The plan was to introduce the topic of addition and subtraction of rational functions. The lesson would start with the rules of addition and subtraction of fractions with the requirement for all terms to have the same denominator. I would then extend that rule and the steps required to obtain same denominators for algebraic rational functions and the need to factor the numerators and denominators of all terms. Since Samantha was only present for half an hour today, I spent time reviewing topics we had covered and giving her a brief look ahead at the material we would be covering next time. There was no assignment.
