Spaghetti sine is an activity that can be used in a grade 11 U/C or grade 11 university level math course to help students understand the sine function. This activity would be used during the trigonometric functions unit.

This activity requires students to cut pieces of raw spaghetti based on a radians/degree wheel. As students start cutting the spaghetti they should start to notice a trend once they make it all the way around the circle for cutting spaghetti pieces. This provides students with a visual representation of where the sine function originates from and can be used to explore other topics such as periods, amplitude and transformations of trigonometric functions.
The next activity was for grade 11 college mathematics and was very practically suited towards choosing an appropriate car insurance company to save you money. The goal of the activity was to figure out how much car insurance would cost with driving school, and whether or not participating in driving school will save you money on your car insurance in the long run. I found this activity very interesting because I love to save money (don't we all?!) so I thought this would be an excellent lesson during the financial unit that will grab the attention of students easily.
