S1.C1.PO1

SWBAT: Recognize, provide examples of and create a hierarchy for all of the real number sets.

- start at 1, 2, 3,…

- start at 0, 1, 2, 3 …

- Positive and negative whole numbers.
… -3, -2, -1, 0, 1, 2, 3, …

- Any number that can be written as a fraction. This includes all terminating and repeating decimals.
( 1 ½ , 8.19, 5, -2, )

- Any decimal that does not repeat or terminate.

- All rational and irrational numbers.

- OBJ: SWBAT determine the difference between finite and infinite sets.
- Standard: S1C1PO2

A set is a group of objects.

Usually in a math class we will deal with sets of

A set could be “the number of people in the room wearing white shoes.” Or, “all objects in the room that are black.”

NUMBERS!

There are three different types of sets:

1. First type is: A finite set.

2. Second type is: An infinite set.

3. Third type is: An empty set

Finite sets have an exact number of elements in the set.

Examples:

{5,6,7,8} or { whole numbers less than 14}

In other words, the set has a stopping point…a last value…a final number…doesn’t keep going…finishes…no mas!

Note: The curly braces {} simply represent a set of numbers…this is called “set notation.”

Infinite Sets have unlimited elements in their set.

Examples:

{ 0, 1, 2, 3…} or{integers less than -3}

You can tell the difference between a finite and infinite set based on whether the set keeps going, or whether the set has a specific number of elements in it.

Always ask yourself: “Self, does this set keep going?”

If it does…then it’s infinite!

Cool huh?!

- The Empty Set is the set that contains nothing. It is called the null set.
- It is represented by either
a { } or ø.
