• How to create a number line    8-27-2018

    1. Draw a line with arrows on both ends (horizontal or vertical)
    2. Add the ticks or slashes in the line about 20 for today’s examples
    3. Place a 0 in the middle and number the number line by 5’s
      1. Negative numbers go to the left of 0 for horizontal lines or below 0 for vertical lines
      2. Positive numbers go to the right of 0 for horizontal lines or above 0 for vertical lines
    4. Plot the points
  • How to add and subtract integers using a number line  8-28-2018

    1. Create a number line
    2. Plot the first number in the expression/ problem
    3. Use the sign to determine the direction
      1. + (addition) move to the right/ positives
      2. – (subtraction) move to the left/ negatives
      3. Note: if there are two negative signs, it changes the original direction
    4. The 2nd number tells you how many units from the first number you are going
  • How to add and subtract integers without a number line  8-29-2018

    1. Adding integers
      1. Subtract the numbers and keep the sign of the larger number
      2. Examples
        1. - p + q
        2. p + (- q) = p – q
      3. Subtracting integers
        1. For a negative number minus a positive number, add the absolute value of the numbers and keep the negative sign.
        2. Example
          1. – p – q = - p + (- q)
        3. For a number minus a negative number, change the subtraction to an addition problem
        4. Examples
          1. p – (- q) = p + q
          2. – p – (- q) = - p + q

     

    Sample problems:

    1. (- 1) + 5
    2. 5 + (- 3)
    3. 7 + 5
    4. – 4 + 7
    5. 7 + (- 8)
    6. (- 6) + (- 3)
