Rock, Paper, Scissors Math Variation To Teach Angles

Most rock, paper scissor, games are played with an odd number of choices in order to optimize each choice. I choose to use four choices obtuse, acute, right and straight

 Obtuse x > 90 degrees


Right Angle 90 degrees 


Straight Angle (line) 180 degrees

Acute Angle x < 90 degrees





So here's how you play
1) Have your kids right down the choices and write their definition as well as draw a picture
2) Provide your students with the rules of play (shown below)




RULES OF PLAY

1) Obtuse Angles beat Acute angles 
2) Acute beats Right and Straight Angles
3) Right angles beat Obtuse angles
4) Straight angles beat Obtuse and Right angles.
