Description
Buying a New TV or Computer
- When you buy a TV, computer monitor, or touch-screen device, the "screen size" is measured as a diagonal line from corner to corner.
- To find the size of your new screen, you can use Pythagoras’ theorem.
- In this home-based activity, students will start by measuring their own TVs or device screens with a measuring tape.
- Then they will use the height and width to find the unknown length of the hypotenuse.
- In the last step, they will check their answer with a measuring tape.
- A bonus question will challenge students to think about the industry practice of using the diagonal length to market screen sizes.
How to Use It: This is a great "do together" activity for parents to do with students at home. The activity is designed for Math 8, but may also be a helpful support in geometry courses.
