Fractions
Whole
A whole is all of the parts of one shape or group.
Partition in fractions
splitting your whole into mulitple equal parts
Communitive Property ? Which Operations?
You can switch the order of your Values but the total stays the same. Addidtion and Mulitplication. 5+4= 9 is the same as 4+5= 9. 3 x 5 = 15 is the same as 5x3= 15
Polygon
2D or flat shape, has straight lines, and is closed
Perimeter? Formula
The total distance around a 2D or flat shape. L+W+L+W= P
Equal Parts
Parts of a whole or parts of a group that are exactly the same size
Numerator
Tells how many parts are being counted
Associative Property
You can group addends or products different way and get the same product or sum.
Parallelogram
A quadrilateral with 2 pairs of Parallel lines, all 4 sides are equal lengths.
Area? Formula
The total space inside A 2D or flat shape. L x W = A
Fraction
A number that names part of a whole or part of a group
Denominator
Tells how many equal parts are in the whole or in the group
Distributive Property
One factor stays the same the other factor will be broken up into two addends
EX: Factor 30= 15+15
Quadrilateral
A 2D or flat shape that has 4 sides
Unit
A form of measurement
Unit Fraction
Names 1 equal part of the whole
Equivalent Fractions
Two or more fractions that take the same amount of space or distance in the same sized wholes.
Inverse Operation
Operations that have a relationship with each other. Addition and Subtraction. Mulitplication and Division.
Rhombus
A Quaderilateral with 4 equal sides
Mass
The amount of matter in an object
Unit Fraction
Names 1 equal part of the whole
Non- Unit Fraction
A fraction that has a numerator greater than one. Unit fractions can be joined to create NON UNIT fractions.
Expression

Congruent
2D shapes that have the same size and the same shape
