Students are introduced to functions by a series of clanking, steaming, and whistling contraptions in the Function Machines 1 Gizmo. Students drag a machine to a stand, select an input number, and observe the output produced by the machine. Using input/output tables, students can then write a rule for each machine.
Once students have mastered one-step machines, they can model more complex functions by stacking machines on top of one another. Students can program their own machines and then challenge their classmates to determine their functions.
After completing the Function Machines 1 Gizmo, students can continue to develop their skills with the Function Machines 2 and 3 Gizmos.
