What’s Goin’ On In Room 133

Posts Tagged ‘9 weeks’

Okay, colleagues, here we go.  Your 9-weeks test is just about here.  I know we’re in the thick part of the schedule but hang in there!  Spring is here, everything is turning green and you guys are just soaking up the math!  Hoo-ah!

You know the test is cumulative, meaning that everything we have covered is going to be on it.  You will do well as long as you remember that you really do know this stuff – stay away from the mindset of “I don’t get it!”.  You really do get it – just give yourself a chance!

Our test is on Thursday so make sure you get plenty of rest.  Go to bed early Wednesday night  and eat breakfast Thursday morning.  It will definitely improve your performance, no doubt.

Okay, colleagues, this is what you’re going to need to know:

Remember coordinate planes?  You’ll need to plot and read a few coordinates and you’ll need to know which quadrant is which. 

You’ll need to do everything with equations that we have covered:  the difference between equations and expressions, the difference between algebraic and numeric; how to form an equation/expression from the written descrpition (such as “Four less than a number is twelve”.  Well, you know that can be written as X – 4 = 12, right?); and you’ll need to know how to solve one step equations (6x = 18, therefore x = 3) and two step equations 6x + 5 = 17, therefore x = 2). 

You’ll need to know how to work with any formula you are given.  Page 131, Section 3-7 in the text; remember that a formula simply shows what the relationship is among different quantities, such as between distance, rate (or speed) and time -> distance = rate X time. 

Or you could be give a formula that was developed to help keep track of inventory or pricing (such as the first item costs $25 and each additional item costs $10).  Either way, if you are given a formula, you should be able to plug in the numbers where they go and chug away. 

By the way:  that relationship stuff sounds very much like our dealings when we looked at proportions and scale.  Might not hurt to take a look-see at that while you’re at it.)

You have had two major quizzes leading up to this test so, along with this guidance, you have enough material to look over.   You should do fine , colleagues – if you’re being honest with yourself. 

Essayons!
