Brief Description:
First the students must choose a game to play.  Then they choose their math level and begin the game.  Students are then given questions in a fast paced setting.  The goal is to complete as many questions as possible in the time limit.  When finished the student is taken to a summary screen that details each question they answered (up to 50 total questions).
Lesson Ideas:
Introduction to Crazy Calculations, Math Skills Review, Timed Challenge
How To Play:
In this activity the goal is speed and accuracy.  First students choose their game options and then click go.  Students will see three spots for questions.  The center spot has the current question, the left displays the last question answered, and the right displays the next question.  As soon as students complete the required amount of questions or the time runs out, they are taken to a summary screen.  This summary screen keeps track of up to 50 questions and allows the final score to be printed.
