Integers in Math

The sixth graders started INTEGERS this week.

Integers are whole numbers that can be less or more than zero. Zero is also an integer.

Negative integers are integers that are less than zero. (-2, -124, -12)
Positive integers are integers that are greater than zero. (3, 123, 13)

Words like profit, increase, and above are often used for positive integers.
Words like loss decrease, and below are used for negative integers.

Opposites are two numbers that are the same distance away from zero in opposite directions. (ex: -2 and 2 are opposite numbers)

Students can also compare integers using a number line.
for example:
1. -3 < 7
2. -6 < 0
3. 0 > -4
4. 5 > -7
6. -9 < 9
7. 1 > -5
8. -11> -12
9. -10 < 8
10. -15 > -16
