This review guide can be used as homework or an in class activity. It also works great for students who have been absent. The questions are numbered in each section so that you have the option of breaking the assignment up into three separate parts; atomic structure, isotopes, and ions. This review guide has varied levels of questions and is differentiated for different learning styles. It is meant for high school students, but would also be suitable in some middle school classrooms. As usual, there is a heavy focus on literacy skills!
