1.6 The Factor "10 Game" Challenge 
Student's page

How to play the Factor
game
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 opponentís 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 B chose. For example, if A chooses 25, then B gets 1 and 5 (since they are factors of 25). At this point A has 25 points and B has 6. And now it is Bís turn to go. The chosen numbers are removed from the screen.
