Why do tires appear to spin backwards in some car commercials? Students apply unit rates and the formula for the circumference of a circle to determine what makes a spinning wheel sometimes look like it’s moving in the opposite direction of the car sitting on top of it.
Geometry (G), Ratios and Proportional Relationships (RP)
How do camera settings affect the final image, and how can we use aperture and shutter speed to take better pictures? Students use the area of circles and fractions to explore how to properly expose a picture, and how photographers use depth of field and motion blur to get the perfect shot.
Should you ever order a personal-sized pizza from Pizza Hut? Students calculate circle areas to compare the unit costs of different sized pizzas, find the percent of pizza that is tasty inside vs. crust, and debate whether it’s ever a good idea to order a personal-sized pizza from Pizza Hut.
Like the jacket, this lesson is for Members only.
Mathalicious lessons provide teachers with an opportunity to teach standards-based math through real-world topics that students care about.
How have video game consoles changed over time? Students create exponential models to predict the speed of video game processors over time, compare their predictions to observed speeds, and consider the consequences as digital simulations become increasingly lifelike.
