Using a number line to add integers

(+2) + (+3) = 5

(-4) + (-2) = -6

3 + (-2) = 1

(-5) + 4 = -1


Positive numbers move right

Negative numbers move left

Number line can be vertical

ID the pattern write a chart, create algebraic equation.

The pattern on the right adds four all the time.

The pattern on the left adds one all the time.

To find how much sticks it takes to make one

house , you how to multiple by 4 and add 1

eg.

1x4=4 2x4=8 3x4=12

4+1=5 8+1=9 12+1=13

5=5 9=9 13=13

How many sticks does it take to make 211 houses?

211 211x4=844

200x4=800 844+1=845

11x4=44 845=845

800+44=844

Integers Cont.

zero pair-a pair of integer chips with one chip representing +1 and one chip representing -1

eg.

Opposite integers - two integers with same numeral but different signs (+,-)

eg.

Show using chips:
