The start of the lesson reviews calculating the mid-point for line segments with different gradients. The development phase builds on this by calculating the gradient of a line segment as a measure of its rate of change. As learning progresses students calculate the gradients between two coordinate pairs.
Differentiated Learning Objectives
- All students should be able to calculate a positive gradient of a linear function using the graph.
- Most students should be able to calculate a gradient of a line segment between two coordinate pairs.
- Some students should be able to calculate the gradient of a function in a real life context.
