PPTs are NOT analysis. They are visuals with the text. I group students and they read and make their own analysis then share with the class. Great activity to help develop critical thinking. Suggested activity is a Venn Diagram in which students compare and contrast each ode. Venn Diagrams can be easily found online: http://www.studenthandouts.com/Assortment-01/Graphic-Organizers/Blank-Venn-Diagrams-Instructions.html
OJO Each one is also available separately on my TPT store.
