1. Whole, Integers, Rational and Natural Numbers M7N1. Students will understand the meaning of positive and negative rational numbers and use them in computation.

2. Natural Numbers Natural Numbers are your normal counting numbers. Examples: 2, 6, 59, 341, 2578, etc. Natural numbers DO NOT include 0, anything with a decimal or fraction, or negative numbers.

3. Whole Numbers Whole numbers are the natural counting numbers, but they also include 0. Examples of whole numbers are: 0, 27, 389, 43, 78, etc. Whole numbers DO NOT include fractions, decimals or negative numbers.

4. Integers Integers are positive and negative numbers and zero. For example, -10, 56, -1, 9, 16 etc. Integers DO NOT include fractions, decimals.

5. Rational Numbers Rational numbers are any numbers that can be written as a fraction, and any decimal that ends or repeats the same number over and over again, including zero. Numbers that can be written as a fraction include: 1/2, -2/3, 15 because 15= 15/1 etc. Repeating decimals and terminating decimals look like this: 2.3333…., -1.27,.66666….., -2.9999, etc. (NOTE: These decimals can also be written in fraction form)

6. Decide what category(s) each of the following numbers fit in to. Example: -27 -27 is an integer and a rational number, because it is negative and can be written as a fraction (-27/1)
