A course that uses problem situations, physical models, and appropriate technology to extend algebraic thinking and engage student reasoning. It includes the study of the concepts of functions, solving equations, slope as rates of change, and proportionality. Students will use physical models to represent, explore, and develop abstract concepts. The use of appropriate technology will help students apply mathematics in an increasingly technological world. Use of graphing calculators is required. Students are required to take the TN Ready Algebra l Assessment Test.
