CCSS.Math.7.EE.1,2(Alg.1a,1b) Distributive Property

Dear Girls and Boys,

Last lesson we were talking about Properties or laws of math.  The 2 properties that are important are - Commutative ( Flipping numbers) and Associative( Flipping parenthesis) PROPERTIES.  Well, the 3rd most important ( actually the first!) is the Distributive Property when you are working in Expressions and Equations.  Distributive Property is the law is like double multiply! For Example: a(b + c) : you multiply the a to b and then multiply the a to the c. The answer would be ab + ac.  I know this is confusing, but after a few examples you will understand completely.  Other  vocabulary terms associated with the Distributive Property are: Terms - Variables - Constants - Coefficients!  You must be able to identify these words in an expression.  
-6 + 6x - 2y + 4 - 10k 
Terms: -6   6x  -2y  4  - 10 k
Variables: x y k
Constants: -6   4
Coefficients: 6   -2  -10

For this Performance Indicator, you will be creating another GRAPHIC ORGANIZER - with all of the properties mentioned so far:  Commutative Property, Associative Property, Identity Property, and Distributive Property.  There is a sample graphic organizer tacked to the board to view. THIS MUST BE STARTED TODAY!!

As always in MATH,
