A starting line and “target line” will be laid out on the floor of the activity area. Students will program their robots to traverse the perimeter of a triangle of specified dimensions. Students will have to use the Laws of Sines and Cosines to calculate the speed, direction, and travel time for each leg of their robot’s travel.
This assessment is used to check for understanding of standard NC.M4.AF.2.3 The assessment is open-ended and asks for students to provide understanding of amplitude, period, phase shift and vertical shift of sine and cosine graphs. It also assesses writing equations of sine and cosine and sketching their graphs.
Students will create their own sine function to match a picture of mountains. This will teach them what the coefficents of trig functions do.
Description of sine function with image, calculation of length of hypotenuse with known angle and opposite side, calculation of angle with known opposite and hypotenuse sides. Explanation of inverse sine. Interactive fill in the blank of main points.
