=Summary=

===Students must create a family budget and determine whether to buy generic or name brand products. This determination will be based on experiments and research done by students of various products and will require a series of mathematical operations for graphing differences in a final presentation. ===

=CCSS Alignment for Grades 6-9=


 * ===**6.RP.3 **. //Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.// Students will use ratio reasoning to express the difference between their observed name brand and generic products. ===
 * ===**7.RP.3 **. //Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.// Students will use ratios to determine highest percent increase in savings when purchasing either name brand, generic, or a mixture of both products. ===
 * ===**8.SP.4. ** //Understand that patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a two-way table. Construct and interpret a two-way table summarizing data on two categorical variables collected from the same subjects. Use relative frequencies calculated for rows or columns to describe possible association between the two variables//. Students will use generic and name brand product to display frequencies and relative frequencies in a two-way table. ===
 * ===**S-ID.3 **. //Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers)//. Students will interpret differences between name brand and generic products according to shape, center, and spread in the context of each data set. ===
