#### .... is saving for (aka Linear relationships)

Christine is saving for a holiday. She is able to save some money per month. To get started Christine's grandparents are going to put in $500.
This is the starting scenario - look at saving $50 per month and then two other options. Looking at the relationship between graph, table and equation of the data in the tables and investigate the link to gradient and y-intercept.
A starting place for a unit on linear graphs (if students don't know gradient, teach it in context or skip that part)
