#2.e Positive/Negative Numbers

M.EE.6.NS.5-8 - Understand that positive and negative numbers are used together to describe quantities having opposite directions or values.

Learning Goal:
• Level 2-3 – I will add positive and negative numbers to solve a math problem and graph the answer.
• Level 1 – I will count objects with negative numbers.

Essential Questions:
• Where can I find this number on a number line?
• Does this number have a positive or negative value?
• What are some examples I can use to show negative and positive numbers?
• If I start with a positive number and then add a negative number, what direction on the number line will I move?
• How far is this number from zero?

Vocabulary:
• Positive numbers - numbers greater than zero; the numbers to the right of zero on the number line.
• Negative numbers – numbers that are less than zero; the numbers to the left of zero on the number line.
• Whole number - a positive integer or zero. 1, 15, 30 and 894 are examples.
• Number line - visual representation of numbers along a horizontal line.

There are many ways that a number line can be a support for math learners:

Determine what number comes next or before another number. 
Sequence numbers. 
Support one-to-one counting. 
In addition and subtraction, start with the first number and move forward or backward by counting how many to add or take away.
