TIMS Task

Use DPP N as a Problem of the Week. Students will need a copy of the Centimeter Graph Paper Master. Make sure students understand what is meant by 3 separate minutes. When students turn in their work, have a discussion with the class about the data they collected. Ask them to interpret each other's graphs and tables.

N. Counting Cars

Count the number of cars passing your house for three separate minutes. If you live on a street where very few cars pass by, you may choose a different street, such as the street at your school or the street at the house of a friend or relative.

  1. Record your data in a table. Record the time of day when you made your count.
  2. Find the median for your data.
  3. Graph your data on a bar graph using a piece of Centimeter Graph Paper.
  4. Compare your graph with the graph of two other students. How busy is your street compared to the other two students' streets?
  5. Use your graph to tell the story about the traffic on your street.
  6. Predict what your graph would look like if you counted the cars in the middle of the night. Would it look different or about the same? What would be different?
