# Q2, W4: November 30th – December 4th Advanced Math Teacher Felicia Taylor Advanced Math 7th 13 Focus 3: Ratio, Proportion & Percent
Standard(s) Taught

4. #### Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate.

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).
