Functions are the basis of algebra and future mathematics. This learning progression covers functions, linear equations, graphing, and generalizing all of it. The assessments will challenge students and ensure that the teacher knows their students have met the standard. The problems used are fun and engaging about real life situations where these concepts can be used. Also attached is a lesson plan about modeling how slopes change as lines change. This lesson uses a program called Geogebra to model the changing slopes for students. This lesson is great for a struggling Algebra class because students are able visually see how the slope changes from positive to zero and to negative. by using this program you are integrating technology into your classroom and grabbing your students attention. This learning progression address the common core standards CCSS.MATH CONTENT.8.F.A.1-A.3 and CCSS.MATH CONTENT.8.F.B.4-B.5. By using this leaning progression you students will learn about functions and have a good time while doing it.
