# Q2, W3: November 16th – 20th Advanced Math Teacher Felicia Taylor Advanced Math 7th 12 Focus 3: Ratio, Proportion & Percent
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…

• compute a unit rate by iterating (repeating) or partitioning given rate.
• compute a unit rate by multiplying or dividing both quantities by the same factor.
• explain the relationship between using composed units and a multiplicative comparison to express a unit rate.
• use measures of lengths and areas to calculate unit rates with the given context.
• analyze ratios in a table to determine if the ratios are equivalent by finding the constant of proportionality.
• calculate the cross product to determine if the two ratios are in proportion (equivalent).
