How many pennies are there in a pyramid of pennies stacked 13 high with a base of 40 by 40 pennies? This problem challenged students to extract information, come up with a plan and work through complex calculations involving very large numbers. Each day as class came to an end and recess was to begin I heard " No, can we stay in" or "For the first time ever I don't want math to end and your telling me I have to stop"... music to my ears! Stay tuned for drawings and explanations of the students solutions. Comments are closed.
