Subtracting integers

1. Write down the problem 2. Lay down the first integer 3. Add zero pairs until you have what you need 4. Take away the second integer 5.. Write your answer

Copy each problem. Draw pictures to show what is happening.

Add zero pairs until you have enough to take away what you need to.

You have to add zero pairs until you have enough to take away what you need to.

Example of great pictures

ADD THE OPPOSITE a - (-b) = a+b

1. LEAVE THE FIRST #ALONE 2.CHANGE FROM SUBTRACT TO ADD 3.OPPOSITE OF THE 2 ND #

Remember…only change subtract to add. DO NOT change add to subtract.
