We have many different kinds of numbers; we have Natural numbers (number {1,2,3,4,5,….} or Counting numbers), Whole number {0,1,2,3,4,….} and we have Interagers {….,-3,-2,-1,0,1,2,3,….}.

when useing negative in math we can become confused very quickly, It seem that as soon as we see the negative symbol (-) our brains freak out. This can be a easy fix if you just have the right tools. Color squares can be big help.

Red- Negative

Black- Possitive

Black + Red = 0

The Picture above are models of using red and black squares to help solve the problems. On the left we have -3 + 5= 2 and on the right we have -5 + 1 = -4.

We can also look at these problems by creating a “sea of zeros” with problem in the center and solve the problem in a different way.

In the picture above we have -2 (the number in the center circle) and we want to take away 3. Our problem is -2 – 3 = ___. We can get an answer by takeing away three of the black squares in the “sea of zeros”, this will leave us with -5.

These are much easier ways to deal with negative numbers. Not only are the helpful but they are easy to understand!
