Y helo thar guys.
If anyone missed today's class, here's how to label your foldable:
What are squre numbers (a.k.a. Perfect Squares)?
They are the product of a whole number multiplied by itself.
Example: 2x2=4. The product is the 4, the whole number is the 2 and its been multiplied by itself, making a Perfect Square.
What are factors?
A whole number which divides evenly leaving no remainder.
Example: factors of 16= 1, 2, 4, 8, 16. These are the factors of 16 bcuz 1x16=16, 2x8=16, 4xitself=16.
It's been color coded. The ones that are the same color are the ones that are multiplied to each other.
What are Prime Numbers?
A whole number greater than 1 that only have 2 factors - 1 and itself.
Example: 2, 3, 7, 11, 13
What are Prime Factors?
Factors that are prime numbers.
Example: What are the Prime Factors of 10:
We're looking for factors of 10 and 8 that have the factors of 1 and itself. 2 and 5 are the ones that fit this description.
That's it for notes. Now for our homework.
Find factors of the following numbers:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12.
An easy way to do this would be to make a multiplication grid. It looks like this:
