ACE 1.1: Ads that Sell

Today we had our first class in small and large groups. Students received their new math book, Comparing & Scaling: Ratios, Proportions & Percents. The big ideas of today's lesson were to explore strategies for presenting quantitative comparison information, and use the language of ratios.

The small groups met with Cory and went over writing ratios and practiced that skill using the handout here. The large group met with Sima and talked about the difference between ratios (which are comparisons of a part to a part) and fractions (which are comparisons of a part to a whole). Both groups worked on problems with survey data comparing preferences in taste tests, interpreting what statements we read in ads might mean; the small group worked on the problem here, and the large group worked on the problem 1.1 in the book. Some students brought in ads for extra credit that used quanitative information to sell their products, and we took a look at those ads as well.

No homework for the small groups.

For the large groups, please choose one of the options below to complete.

Option 1
Problems 1-2 and 11 on pages 10-13

Option 2
