Good day to all of you,
We are moving onward with algebra. From the last lesson, you learned that the number beside the variable is called the COEFFICIENT- now this is the number only ( and the number takes the sign) of the algebraic expression. For instance, -9x the coefficient is -9, the term is -9x, and the variable is x. Make certain you can identify these parts of an expression. There will be a quick quiz and if you are reading this, it will not be a pop quiz to you!
Onward to todays lesson....... we are talking about Sequences. Sequences are patterns in math. Generally, you are talking about numbers, so we are always looking for patterns in math. This is fairly simple and as you go through the examples on the videos, I do believe that you will catch on fairly fast.
The second lesson in these videos are on the Commutative and Associative Properties. Properties are the laws or rules of math that we have. The first law, the commutative property is where you flip around the numbers when you add or multiply. For example: 3+4 =4+3 AND 3(4) =4(3) . This is not so for subtraction or division. Associative Property is when you keep the numbers the same, but flip the grouping ( ) around. For example: 3 + (4 + 5 ) = ( 3+4 ) + 5 and 3( 4*5) = (3*4) 5. Just like the commutative property, this does not hold true for Subtraction or Division. Go through the worksheets and check these out. If you have questions, ask away.
Homework: Read the blog, watch the videos and take notes in your graphic organizer.
As always in MATH,
Mrs M
