of the Unit
The sample investigation below is the first investigation of the unit. In this investigation, students are asked to think about the problem of estimating the rate of change at a specific point in time for three continuously changing phenomena—height of a bungee jumper, motion of a person walking toward and away from a motion detector, and profit of a business. In each case, they are asked to use graphs and tables of sample values for each variable to estimate instantaneous rates of change.
Throughout the curriculum, interesting problem contexts serve as the foundation for instruction. As lessons unfold around these problem situations, classroom instruction tends to follow a four-phase cycle of classroom activities—Launch, Explore, Share and Summarize, and Apply. This instructional model is elaborated under Instructional Design.
