Teacher Lesson Plan
Simulating the activity: (Suggestion: Use 2 measuring cups with tape marking the 6 oz. line on one cup and the 10 oz. line on the other cup.)
Specific instructions for using the ESCOT Runner software to interact with the Pirate Diamond Activity can be viewed here.
ESCOT Problem of the Week hosted by the Math Forum Part I:The setting is given:Part II:The pirate ship has just landed, loaded with diamonds. You've been sent to buy 8 lbs. of diamonds but you only have one 10lb. and one 6lb. measuring container.You will be asked to respond to this question: Can you measure 1 lb. of diamonds using only one 10lb. and one 6lb. measuring container? How about 2 lbs.? Consider the amounts between 1 lb. and 16 lbs. What conclusion can you make about the amounts of diamonds that can be purchased using only one 10lb. and one 6lb. measuring container?Part III: You now have a choice of five pairs of containers to use for measuring. For each pair of containers, can you make the purchase of 8 lbs. of diamonds? For those pairs that work, how can you make the purchase?Part IV: There is a counter which keeps track of the number of times you have emptied a container. You may have noticed that you end up emptying the containers quite often, which seems like a waste of time. Also, the pirate is liable to make you walk the plank if you empty the containers too often because you are handling his diamonds too much.
At this point, you have investigated the problem using manipulatives (containers) and technology (the ESCOT Runner simulation).
