• Math Bowling

  • • You roll 3 dice and manipulate the numbers in as many ways as possible to try to “knock down” the bowling pins (circles numbered 1-10 on a piece of paper, arranged like bowling pins). You get two rolls per “frame” before totaling up the number of pins you knocked down. For example, if I rolled a 1 ,2 and 3 I could knock down the following pins:

1+2=3

3-2=1

2x1=2

3x2=6

3+2=5

3+1=4

3x2+1=7

(3+1)x2=8

Then on my second roll, I would try to manipulate the numbers to knock down the 9 and 10 pins.
