Adding and Subtracting Positive and Negative Numbers

Toady in math we are working on adding and subtracting positive and negative numbers. Mrs Sims took us outside in the hall and showed us how to do this......

First she gave us sticky notes with positive and negative numbers from +21 to -21. Then we stuck them on the wall in order, like in a number line. After that she wrote a problem on her slate and showed us how to solve it. 

Let's say that you have -10+6. First you would start at the zero and face the side with the positive numbers. Then you would say the first word in the problem. Negative is the first word. So then you would flip around facing the negative side.  After that you would go to negative 10. Plus is the next word you hear. You would face towards the positive side and would add or move forward six. Or answer or result would be -4.

We had fun today learning about adding and subtracting positive and negative numbers today!!!!!!!
