AIM: What do different comparisons tell us about their relationships?
HW: ACE #1-5, p.19-20
Classwork: Today marked the beginning of Unit 3- Proportional Relationships. Last unit on similarity set the conceptual foundation which we will build upon with proportionality. We began today's lesson by examining common product comparisons we see on TV and in print media (T-Mobile vs. Verizon; Crest vs. Colgate; Advil vs. Tylenol; Android vs. Apple). Some advertisements and articles compare products with percents, fractions, and words, all of which are ways to express ratios. We discussed the idea of surveys and how they are important in gathering information for market research. Once the information is gathered, decisions can be made based on that data.
Students took the role as marketing executives for a soda company, Bolda Cola. It's biggest competitor is Cola Nola (think Pepsi vs, Coca Cola). They were given some statistics from a survey and needed to decide which to use for an upcoming television advertisement. This lesson sets the stage for proportional thinking in the rest of the unit.
