STEPS TO SUBTRACTING INTEGERS

Page 4: 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.

REMEMBER ZERO PAIRS…..

Page 5: 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.

Copy each problem. Draw pictures to show what is

happening.

Page 6: 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.

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

Page 7: 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.

Page 8: 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.

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

Page 9: 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.

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