Which TV is the Best Deal?


Check out the TVs.  All have essentially the same features, only the size of the screen varies.  Which TV do you think is the best deal?

Explore area and unit pricing to determine which HDTV offers the most screen area for the price. Students use scale diagrams to find the area of various HDTVs and make comparisons in actual screen area. Students discover that the diagonal length of an HDTV is not proportional with the screen area of the HDTV. 

Technology: You might use this TV size calculator and comparison tool from TVCalculator.com to impress this on students.  In this lesson students work with the ideas of area, similar figures and unit rate.
