- Download the weekly worksheet. You can print it out or copy the information onto a piece of scrap paper.
- Write down the number of miles your car is driven each day and how many miles per gallon (MPG) your car can drive.
- Write down the numbers on your car's odometer
- Write down each day's number on your tracking sheet. If there are days you don't read the odometer, just leave those days blank.
- Write down your car's miles per gallon (MPG). If you don't know your car's MPG, just write down the kind of car it is.

- Enter your results right here in one week.
- Can you drive fewer miles next week?

- When you fill up the tank, write down the number of miles on the odometer.
- The next time you fill up the tank, write down the number of miles that are on the odometer this time.
- Write down how many gallons of gas went into the tank too. (This number will be on the gas pump.)
- Subtract the number of miles at the first fill-up from the number of miles at the second fill-up. This is how many miles you drove between filling the tank.
- Divide the number of miles you drove by the gallons of gas you put into the tank the second time you filled-up.
- The number you end up with is the number of miles your car drove on a gallon of gas: your car's miles per gallon or MPG.
