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.
