Method for visualization

create a number line going from -4 to 13 with 0.5 increments

• When trying to determine if a number is greater choose the starting number. If the number you are trying to determine is larger is further to the right on the number line, it is in fact larger.

ex. -3 is further to the right than -3.5, making it greater

• When trying to determine if a number is smaller, choose the starting number. If the number you are trying to determine is smaller is further to the left on the number line, it is in fact smaller.

ex. if we go to 12 and go to the left we will eventually get to 2, meaning that 2 is smaller than 12
