Business Cycle Worksheet

The business cycle is easy to draw as a wavy line on a whiteboard and much harder for students to actually read once real numbers are in front of them. This worksheet closes that gap with a single real GDP series across eight periods. Students sketch the curve themselves, then place the four business-cycle labels — peak, recession, trough, and expansion — onto the specific periods where they belong, rather than onto a generic textbook diagram.

Part 2 raises the difficulty by asking students to add a second line: unemployment. Instead of handing them a definition ("unemployment moves opposite to GDP"), the worksheet gives them that one fact and asks them to apply it to the same eight periods, predicting whether unemployment is low, rising, high, or falling in each stretch of the cycle. Part 3 closes with a short paired explanation of why that inverse relationship holds, using the idea that firms hire and fire based on how much they're selling.

Plan for 20 to 30 minutes: roughly 10 minutes to sketch the curve and label the four phases, 10 minutes to work through the unemployment predictions, and the rest for the paired explanation in Part 3. This works well right after a lecture introducing the four phases of the business cycle, since it asks students to apply the vocabulary to real data rather than just define the terms.

Because the GDP numbers are given as a small table rather than a pre-drawn graph, students who struggle with reading data will need more support in Part 1 than students who are just shaky on the vocabulary. Circulate early to catch anyone who is stuck on the graphing step before they move into labeling.

The eight-period series is short on purpose. A textbook business-cycle chart usually spans decades and compresses the turns into smooth curves, which makes the peak and trough look obvious in a way real data rarely is. Here, students have to find the turning points themselves in a small enough dataset that a mislabeled period is easy to catch and correct on the spot. That also makes this a good whole-class check before moving into a longer, messier real-world GDP series, since students who can label eight clean periods correctly are ready for something closer to actual economic data.

Pair this with a quick review of what "real" GDP means versus nominal GDP if you haven't covered that distinction yet, since the worksheet assumes students understand the numbers are already adjusted for inflation and reflect actual output, not price changes.

This activity is from Module 37 of the Rapunzl curriculum, Unemployment & Economic Growth.

Label the Business Cycle

You will read a real-GDP curve, label the four phases of the business cycle in the right places, and then match a companion unemployment line to it.

Part 1: Label the four phases

The table below is a wave of real GDP over eight periods. First, sketch the numbers as a simple line (period on the bottom, GDP going up). Then label where each of the four business-cycle terms belongs: PEAK, RECESSION, TROUGH, EXPANSION.

1. At which period does real GDP reach its peak before turning down?
2. During which periods is the economy in a recession (GDP falling)?
3. At which period is the trough (the low point)?
4. During which periods is the economy in an expansion?

Part 2: Add the unemployment line

Unemployment moves opposite to GDP over the cycle. For each period, predict whether unemployment is likely LOW, RISING, HIGH, or FALLING, based on your GDP labels.

Part 3: Explain the link

With a partner, explain in two or three sentences why unemployment typically rises during a recession and falls during an expansion. Use the idea that firms produce and sell less in a downturn, so they need fewer workers.

Teacher Notes

The most common stumbling block in Part 1 is confusing the peak with the highest number in the table and the trough with the lowest number, without accounting for the direction of change around it. A period can have a high GDP value and still not be the peak if GDP kept climbing after it. Have students point to the exact period where the line turns from rising to falling, and treat everything before that turn as expansion and everything after as recession, down to the low point.

In Part 2, watch for students who assign LOW or HIGH to every period and skip RISING and FALLING, which usually means they're thinking about unemployment level instead of unemployment's direction of change, the actual skill this activity is testing.

For Part 3, a strong pair explanation names the mechanism specifically: falling sales lead firms to cut costs, and labor is often the first cost cut. A weak explanation just restates that recessions cause unemployment without saying why.
