JOURNAL #20 OCTOBER 4, 2011

TAKE OUT BOTH PARTS OF 2.2 TO CORRECT. STAPLE THEM. YOU NEED 2 NEW PIECES OF

PAPER

Page 2: 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

CHAPTER 2.3Subtracting integers

Page 3: 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

1. Write down the problem2. Lay down the first integer3. Add zero pairs until you have

what you need4. Take away the second integer5. . Write your answer

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.

Example of great pictures

THERE HAS TO BE AN EASIER WAY!!!

ADD THE

OPPOSITEa - (-b) = a+b

Page 13: 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

1. LEAVE THE FIRST #ALONE

2.CHANGE FROM SUBTRACT

TO ADD

3.OPPOSITE OF THE 2ND

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