Introduction to Visualizing & Graphing Sine & Cosine Using Pretzels Exploration

Help students make connections while introducing the graphs of sine and cosine using mini pretzel sticks or equivalent manipulatives. Within this lesson, students will be able to interact with both the sine and cosine graphs using manipulatives such as string and pretzel sticks as they form a tactile graph in groups or individually. A thorough instruction sheet is provided to ensure all students are equipped to create their own pretzel graph. You can also substitute spaghetti, straws toothpicks or any similar item to create a similar experience.

This lesson can be aligned to AP Precalculus Section 3-5.
