Ratio, Proportion, RE and SETS

Dear Samwelli, thank you SO much for sharing all of this lesson planning information! This is EXACTLY what I needed for a Case Study example in my M.Ed. - Education Technology/Distance Learning class where we must create an Instructional Design project. Our project is to show instructors of developmental math programs how they can integrate Khan Academy resources into their existing curriculum. What I NEEDED for the Case Study was a base plan -- I was hoping for just a lesson plan, but here I have found ALL that I need! PERFECT. Thank you!!!
