IntegersIntegers include three groups of numbers

- Counting (positive numbers)- The opposites of counting numbers (negative numbers)- Zero

Negative numbers are always shown with a negative (-) sign. Positive numbers do not need to have a + sign.

Integers­ negative numbers are located to the left of zero and positive numbers are located to the right of zero.

­ the magnitude of the integer determines how many units from zero the integer is.

each negative number is the mirror image of a positive integer with respect to zero. (They are the same distance from zero.)

­ Zero is neither positive nor negative.

­ Negative numbers are all less than any positive number.

A number is 12 jumps away from its opposite on a number line. What could the number be and how do you know. Use words, numbers and pictures.

Filll in this number line:

Explain, in writing why ­4 and +4 are closer to each other than ­6 and +6.

Explain why an integer is never an odd number of jumps away from its opposite on a number line.

Questions to ask yourself when placing numbers on a number line:

­ Is the integer positive or negative?

­ Is this integer located to the left or right of 0?

­ How many units from 0 is the integer?

Place these integers on the number line. Choose your own endpoints and benchmarks.

Comparing Integers­ When comparing integers, place them on a number line and the number to the right is always greater than the number to the left 

Ex. Which number is greater? ­8 or ­5

­ We use less than (<) or greater than (>) symbols tocompare numbers.

­ The bigger end always pointsto the "bigger" number. The smallerend always points to the "smaller"number.

Choose two negative integers. Compare these numbers by describing a situation in which they could be used (temperature) and use this situation to compare using the less than / greater than symbols.
