Boutique - Making Change |
|
At the Boutique shop the student plays the role of a store clerk who sells clothes. The main task is to handle the exchange of money and give correct change. In this example, the student is given $5.00 for an item that costs $4.22. The right change is 78¢. Assuming you have 9 of each coin (quarters, dimes, nickels and pennies) in your register, what are the different ways you could make the necessary change? |

Factor Game – NCTM Version |
|
Two players compete for high score by picking numbers from a screen which are then added to their score. There is a catch though. Whenever Player A picks a number, the total of every factor of that number still showing on the screen is added to the opponent's score. When the opponent, Player B, chooses a number, that number is added to his/her score, but Player A gets the total of all remaining factors of the number that B chose. |
