Upon reflection, Shari and I changed the sequence of the lesson.  For instance, we taught inverses after reflections because they are after all reflections.  We then did stretches, combinations and will do review.  We have added slides and updated the stretches and combinations lessons.  Please note that there is an error in the last example of lesson 3. reflections.  We will be updating that as well.  We hope you are all having a great startup.  Ronni & Shario
