Teacher's field guide

What Students Need to Do: Students read economic charts and graphs, checking the axes, units, and time period. They describe patterns in the data and use those patterns to make a reasonable prediction.
What Mastery Looks Like: A student can point to specific values that show a rise, fall, or change in direction. They can predict a likely next value and explain why the data does not guarantee it.
Common Misconceptions: Students may read a steep-looking line as a large change without checking the scale. They may treat one unusual data point as the trend or state a prediction as a fact.
How to Assess It: Draw a line graph of monthly unemployment rates: January 4%, February 5%, March 7%, April 6%. Ask students to describe the trend, predict May's rate, and cite two values that support their prediction.

Lesson moves
