Greatest Common Factor and Lowest Common Multiple
Steps to calculate The GCF and LCM for a pair of numbers
Step 1- Find the Prime factors for each of the numbers.
Step 2 - Compare the prime factors using a Venn diagram.
Step 3 - To find the Greatest Common Factor; multiple the factors that are common to both numbers, this total is the GCF
(factors found in the overlap of the circles)
Step 4 - To find the Least Common Multiple; multiple all the factors found in the Venn diagram, this total will give you the LCM.

Decimals
A Terminating decimal is a decimal that has an end value example 2.054
A Repeating decimal there are a series of digits or a single digits that repeats
Examples 0.3333333333333 can be written in Bar notation as 0.33 with a line over the 3
Example 0.123123123123 can be written in bar notation as 0.123 with a line over the 123
Example 0.453654363636 can be written in bar notation as 0.45365436 with a line over the last 36
Bar Notation shows what digits are repeating.
When a Value is multiplied by a decimal the product is less than the original number
When a Value is divided by a decimal the quotient will be greater the the original value.

Measurement
We work to find the area and or the perimeter of various shapes.
Perimeter is the length around the shape found by adding all the side lengths together
Area is the space that a shape covers or the space inside a 2 D shape
