**Essential Question: How do I put positive and negative numbers in order? **

a) Keeping score in MathMania.
=== Positive, negative, and 0 terms mean in MathMania is, which ever team answers a question correctly gains points which are positive numbers, and whoever answers a question incorrectly, is losing points which are negative numbers. When a team is on 0 it means that, the team is losing the same points as they gain which makes their score a 0. ===

b) temperature reading.
=== When reading the temperature you use positive, negative, and 0 terms to see if the readings are below or above 0. When a temperature is above 0 it means the temperature will be a positive number. When a temperature is below 0 its a negative number which makes it freezing. When a temperature is 0 it means that it is in the middle of the positive and negative readings. Starting from 0 and below the temperature will be freezing. ===

=
Two decide whether two positive numbers are greater to one another you have to see which number is farther away from 0 and which number is greater. For example- 53 >35. Since 53 is farthest away from 0 its greatest and 53 is a larger number than 35.=====

=
To determine which negative number is greater you have to see which number is closest to 0, that number will be greater than the other number. For example- -4 > -10. -4 is greater because its closest to 0 and -10 is farthest from 0.=====

=
To determine if a positive number is greater than a negative you will have to know that a positive number is always greater than negative since its less than 0. For example- 5 >-9. Since 5 is a negative number it will always be greater than a negative number like -9.=====

3)Describe how to locate numbers on a number line. Use examples to illustrate your thinking. Be sure to include positive and negative numbers as well as fractions and decimals in your examples.
=== To find a number on a number line, you will have to know that the positive numbers will be on the right of 0 and the negative numbers will be on the left of zero. to locate a number like -9 you will have to look on the left of 0 since its a negative number. To locate a number like 9 you will have to look at the right of 0 since its a positive number. ===
