Activity 01
Field Tally: Vehicle Counts
Choose a safe observation point. In pairs, students use tally charts to record vehicle types and directions every five minutes for 30 minutes. Back in class, combine data to create bar graphs showing peak times.
What data do we need to collect to understand traffic flow in our local area?
Facilitation TipDuring Field Tally, have students practice counting silently for one minute to ensure accuracy before starting real data collection.
What to look forProvide students with a blank table showing hours of the day and columns for different vehicle types. Ask them to fill in hypothetical data for one hour of peak traffic and one hour of off-peak traffic, then write one sentence explaining the difference.
