# Direct Linear Proportion

Students learn how to model variables in direct linear proportion using the constant of proportionality, K.  As learning progresses students both derive and use the constant of proportionality to calculate unknown values.
##### Differentiated Learning Objectives
• All students should be able to derive a formula using the constant of proportionality to describe how two measurements are in proportion.
• Most students should be able to derive and use a formula with the constant of proportionality to calculate measurements that are in direct proportion.
• Some students should be able to solve problems in context by deriving and using the constant of proportionality.
