This lesson unit is intended to help you assess how well students are able to interpret distance–time graphs and, in particular, to help you identify students who:

• Interpret distance–time graphs as if they are pictures of situations rather than abstract representations of them.
...

This lesson unit is intended to help students judge the accuracy of two different approximations to a particular linear relationship. Students will compare two linear functions as approximations to the relationship between Celsius and Fahrenheit temperature and consider under what circumstances...

Students will model the data with both a linear function and an exponential function and use it to predict the CO2 concentration in the year 2050 and also when the CO2 concentration will be above 500 parts per million. Students will discuss and document which model makes a better prediction and...

Students will analyze the rising cost of tuition to make a recommendation of which university/college is a better financial decision.
