Unit 9, Lesson 6
Using and Interpreting a Mathematical Model (Optional)
Grade 8
Preparation
Lesson Narrative
To complete this section, in this optional lesson students analyze their model and use it to make predictions and draw conclusions (MP4). Students validate their model by seeing how well it predicts the actual temperature for locations that were not included in the original data. They also look for and investigate outliers in the data. Finally, students interpret mathematical features of their model (slope and intercepts of the line) and discuss limitations of the model.
- Interpret a scatter plot and line of fit that model temperature and latitude, and explain (orally) limitations of the model.
- Use a mathematical model of bivariate data to make predictions (in writing).
Let’s use a model to make some predictions.
