Teacher's field guide

What Students Need to Do: Students read economic charts and graphs to find patterns over time. They use data points to explain a trend and predict what might happen next.
What Mastery Looks Like: A student can point to exact dates and values that show whether prices or unemployment rose, fell, or stayed steady. They can make a prediction from that pattern and say why it is not certain.
Common Misconceptions: Students may call a graph falling because its last point drops, even when the overall trend rises. They may miss the units on an axis or treat a prediction as a fact.
How to Assess It: Draw a fictional shop's monthly sales graph: January $100, February $120, March $140, April $160. Ask, "What is the trend, what might May sales be, and which two points support your answer?"

Lesson moves

Give pairs bread price cards for four months: $2, $2.25, $2.50, $2.75; have them plot the points on graph paper.
Draw bus fares rising from $2 to $3 over three years; ask, "Is a $4 fare next year certain? Why not?"
Make mini graphs from 2,3,4; 4,3,2; 3,3,3; and 2,4,1; students sort trends and discuss which forecast is least reliable.
Print a local gas price history chart from AAA; students cite two months and predict next month's price with a caveat.
