Some data just doesn't follow a straight path. Learners use line graphs to represent data that changes over time. They use the graphs to analyze the data and make conclusions.

Determine the average on a curve. The class finds graphical representations of averages and expresses them both symbolically and on the graph. The assessment requires class members to justify using average to describe graphs.

Is it really that big of a deal if the global climate undergoes a little change? Young environmentalists consider this very question as they discuss in small groups the impact of different climate change scenarios on their lives,...
