Families of Rectangles
Students create a family of similar rectangles and then write the equation of the curve that will connect the upper-right vertex of each rectangle. Students will then create a family of rectangles that have the same area and will write the equation of the curve that connects the upper-right verti...https://education.ti.com/en/activity/detail/families-of-rectangles
Trig Patterns
In this activity, students will use the unit circle to examine patterns in the six trigonometric functions. Students will compare angles created with the x-axis in all four quadrants and discuss with one another what is happening at each coordinate as they move the point around the circle.https://education.ti.com/en/activity/detail/trig-patterns-@ns
Conditional Statements
In this activity, students construct examples of conditional statements such as parallel and perpendicular lines. After completing the conditional statement, they will write the converse, inverse, and contrapositive and determine if each is true.https://education.ti.com/en/activity/detail/conditional-statements
Basic Trig Transformations- 84
In this activity, students will use the Transformation Application to change the values of parameters in trigonometric functions and to determine the effect that each change has on the shape of the graph. Students will then use this knowledge to write equations for sine and cosine functions.https://education.ti.com/en/activity/detail/basic-trig-transformations_84
