Task goals
- Foundation: Read values, intercepts, and simple gradients off a given real-world graph (e.g. distance-time) to answer direct questions.
- Proficient: Sketch a graph from a worded real-world scenario and identify key features such as turning points, intervals of increase/decrease, and rates of change.
- Excellence: Construct and justify a graphical model for a multi-stage real-world situation, using it to solve a problem and critically interpret the limitations of the model.
