2. Divide students into groups of four. Give each group a “How Many Pennies” recording sheet, $2.00 in cents (pennies), an age appropriate balance or scale, and a tray containing the “Common Items” listed under Materials (offline).
3. In their groups, have students use their own “body balance” (comparing the weights in their own hands) to estimate the number of cents (pennies) it will take to equal the mass of each item on their tray. Students should record their estimate on the “How Many Pennies” recording sheet.
4. Students will then use the balance and the pennies to measure the mass of each object, and will record their findings.
