# Activity: Counting Cars

Count how many cars pass by on the road. Make sure you do the counting from a safe place! |

Choose a time, say from 11:00 to 11:10 in the morning

- If you count for 10 minutes, then you can multiply by 6 to find how many cars per hour
- If you count for 15 minutes, then you can multiply by 4 to find how many cars per hour

Use Tally Marks to help you keep count |

You can use this form. Write down the time you start, and when you finish.

Start Time | End Time | Tally Marks | Total |

__ : __ | __ : __ |

Cars Per Hour = ________

OK, off you go!

Note: If you are in a class, then each of you could choose a different time, and the teacher could put all the results together in a nice Line Graph.
