# Q2, W6: December 14th – 18th Regular Math

Teacher Felicia Taylor Regular Math 7th 15 Focus 3: Ratios and Proportional Relationships
Standard(s) Taught

1. #### 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.

Learning Targets and Learning Criteria

Students are successful when they can…

• analyze ratios in a table to determine if the ratios are equivalent by find the constant of proportionality.
• calculate the cross product to determine if the two ratios are in proportion (equivalent)
• graph ratios on a coordinate plane to determine if the ratios are proportional by observing if the graph is a straight line through the origin (y = kx, where k is the slope/ constant of proportionality).
