7.RP.2a

7.RP.2a. Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.

- Starts with identifying whether values given in a table are proportional or not...based on prior work in 7.RP.1 with ratio tables. Then students sort 6 tables into "Proportional" or "Not Proportional", glue onto sheet and graph the relationships. Students should then identify that graphs of proportional relationships form a straight line that passes through the point of origin. Much of this is modified from EngageNY-.That site has some really good stuff- just trying to make it a bit more interactive.
 * [[file:Proportional or Not Tables.docx]]- tables (4 sets to a page) to cut and paste, as well as graph paper/recording sheet.
 * [[file:proportional or not exit ticket.pdf]]- exit ticket to assess understanding of whether values in a table or graph represent proportional relationship.
