Modelling Inverse Proportion

Students learn how to model inverse proportion problems using the constant of variation, k.  As learning progresses students begin to consider non-linear indirect variations.
Differentiated Learning Objectives
• All students should be able to derive a formula in the form 1/x to model inverse proportion.
• Most students should be able to derive a formula to model inverse proportion and use it to calculate unknown values.
• Some students should be able to derive and use a formula to model when one unit is inversely proportion to the square or cube of another.
