Ask and chart responses:
What are some challenges of riding the subway?
How can we help people get to where they’re going quickly and safely?
Explain the key takeaways from the “Do In Advance” teacher reading: that two of the most important factors are overcrowding and out-of-date signals. Note that today’s lesson will focus on overcrowding.
Break students into three groups. Each group will cycle (in partners) between three stations. Place at each station one of the provided print-outs that shows a solution to subway overcrowding and a large piece of chart paper with a T-square (“good idea” and “bad idea”) where students can post their reactions.
Station One: Open-Gangway Subway Cars
Station Two: Build More Subway Lines
Station Three: Build Longer Platforms and Longer Trains
Have students work with their partner at each station. Encourage them to focus on the following questions:
What do you see?
Identify the solution.
Is it a good idea or a bad idea? Why or why not?
Have students write responses on sticky notes and print their name at the bottom. Then they can put their notes on the chart paper within the appropriate side of the T-square.
Rotate groups after 10 minutes.
