Sample Activities:

 

·        Students try to identify fake "bargains" or misleading information from store advertisements, and try to determine which of several options is the best. For example: Which of the following offers the cheapest price?

o       XYZ Mega-Deal Tuna=10 oz can for $2.80,

o       ABC Tuna= 3 oz can for $0.87, 

o       Aunt Betty's Best Tuna=4 oz can for $1.04

 

·        Students plan a fantasy driving trip to Walt Disney World for their family. They research and consider the variety of expenses to be incurred - lodging along the way and at the park, meals, souvenirs, gasoline, admission, and so on. A reasonable budget for the trip is the centerpiece of a report prepared by each student group. Their reports are assessed using a scoring rubric that includes mathematical correctness as well as creativity.

 

·        Students use play money to model decimal numbers. They use decimal language and find fractional equivalents for each coin. For example: a dime = 0.1 = 1/10 = 1 tenth.

 

·        Students first estimate and then use a calculator to find out how long it would take to spend one million dollars at a rate of one dollar per second.
