With a focus on functions, examine some digital manipulatives, spread sheets, and Geometer's Sketch Pads designed to bring movement to a math lecture or lab. Hear a slope. Go from slope to difference quotient to derivative. Use termtiles then sketchpad to compose functions to illustrate (line)(line)= (quadratic). “Concretely” translate and reflect graphs. Easily graph functions, composit functions, inverse functions. Graph Asin(Bx-C)+D by just changing the variables. Compute compounding, exponential, logistic, normal, ... models. All material, including Geometer’s Sketchpad, is now free. Come play.
