These 124 Powerpoint lessons work hand in hand with the Saxon Algebra 2 math textbook. If you do not teach the Saxon program then these Powerpoints can be used to help teach the Secondary 2 Common Core. Each Powerpoint consists of a lesson overview which includes formulas and direct instructions. After that there are several practice problems that allows students to put into practice what they just learned. This is a great opportunity for group work as well as for the teacher to walk around the class and monitor student work. There are a couple lessons missing mainly because proofs are easier to teach without a Powerpoint and more of a discussion and discovery. I have also noticed that when downloading Powerpoint Presentations that the formatting may be a little off. You may want to review each one before presenting to make sure everything lines up.
