Number Lines

Today we really dived into using number lines as a strategy for solving subtraction.
There are two ways to do it.
We can start at the big number and then make jumps back until we've jumped the whole number.
We can start at the little number and make jumps until we get to the big number.
I personally like the second method because I think it is easier to add than subtract.
