Week of January 19th and 26th
Geometry - Chapter 14
Lines, Angles, Quadrilaterals.
Quiz- Jan. 29
December
Perimeter - the distance around a shape
Square unit - a unit for measuring area
Unit square - a square with a side length of one unit
Area- the number of square units needed to cover the inside of a region or plane figure
The formula for finding the area of a square or rectangle is length times width
A= L x W
***We are taking timed multiplication facts tests. One test will be given each week for nine weeks (ungraded), and I will grade the tenth test as a classwork assignment.

Commutative Property of Multiplication (Order Property)
2 X 3 = 3 X 2
Associative Property of Multiplication (Grouping Property)
(2 X 3) X 4 = 2 X (3 X 4)
Identity Property of Multiplication
2 X 1 = 2 47 X 1 = 47
Zero Property of Multiplication
2 X 0 = 0 123 X 0 = 0
Distributive Property of Multiplication
12 x 4 = (6 X 4) + (6 X 4) 12 X 4 = (12 X 2) + (12 X 2)
"Addition Properties"
Commutative Property of Addition (Order Property)
2 + 3 = 3 + 2
Associative Property of Addition (Grouping Property)
(1 + 2) + 3 = 1 + (2 + 3)
Identity Property of Addition
1 + 0= 1
130 + 0 + 130
