In class we made a movie about adding and subtracting integers. Here is my movie.
This is what I know about adding and subtracting integers:
a zero pair is both positive(s) and negative(s)
when adding a negative and positive, you look for the largest absolute value to see if the answer is negative or positive
you can use a number line or integer chips to solve the questions
subtracting negatives, you just add more negative chips since you're just removing, and remove what needs to be removed
number line; put a starting dot to where you start, make an arrow to the answer, write the question on the arrow, then circle the sum
-37 + -41 = owe 37 and owe 41= owe 78
integers scripts: +3 + -2 = +1 [you put 3 positives on your paper. You put two negatives on your paper. Then find your zero pair and circle them. You are left with one positive.]
absolute value: holds the value of what it is we are talking about.
