Grocery Store Math

Have students list their favorite foods. Ask them to look at the packages to see how much food is in each package in both English and metric units. (Both are usually listed.) Then have them go to the grocery store and find out the prices of these foods. Was the price more or less than they thought? Ask students what this told them about the price of food. Did they notice anything about the price of food when it is bought in bulk as compared with when it is bought in small amounts?

History of the Meter

Challenge students to trace the history of the meter. Ask them to find out when and how the length of the meter was first established. Then have students explore how the method tof establishing the scientific length of the meter has changed over the last 200 years. Have students write brief reports to present to the class.
