Linear Functions
Worksheets in which students meet the linear function as a constant rate of change between two quantities, not as a formula to memorise. They start with situations and tables of differences, then move on to proportional relationships, the y-intercept as a starting value, slope as a ratio, graphs and equations in both directions, motion graphs and modelling. The sheets use the Line Explorer, Motion Graphs, Geoboard and Grapher apps.
