# Q2, W6: December 14th – 18th Advanced Math Teacher Felicia Taylor Advanced Math 7th 15 Focus 3: Ratio, Proportion & Percent
Standard(s) Taught

#### Use proportional relationships to solve multistep ratio and percent problems.

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)
• 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).
• calculate the constant of proportionality / unit rate from a table or diagram.
• compute the rate of change/ slope from a graph or equation (k in y=kx).
• solve equations created from proportional relationships.
• write an equation from a proportional relationship.
