Directions:

Dirt Bike Proportions is a multi-player kid’s educational racing game for finding equal proportions, in which students will have to win a motorbike race by solving math exercises fast and correctly. Although this game is organized as motorbike race, students will not drive the motorbike; they will only have to solve proportions. The right answers will help the student’s bike advance. If students make a mistake, the opponents will overcome them. Student’s goal is to manage to get to the finish line first to win. Think fast and give only right answers to win the game. Your students can choose their bike and play the game by themselves or with maximum 3 other students for one game.

 One player: your student will choose a bike and race with 3 computers or people

from public lobby.

 Group of students: have your students click on the box “create game”=>

“private”=> create a password.

Students in this group will do the same and enter the password to play

together.

Students will use the mouse to click on one of the given numbers which they believe will create an equivalent fraction with the given fraction. How quickly the student correctly answers the ratio problem determines how quickly the dirt bike will go. The student with the fastest rate of correct answers will win the race. Hits and misses are recorded and displayed at the end of the game, along with the student's rate.

Students can play other races when the old race is finished.
