This Blog exists for the collective benefit of all algebra students. While the posts are specific to Mr. Chamberlain's class, any and all "algebra-ticians" are welcome. The more specific your question (including your own attempts to answer it) the better.
For the NJ Ask, will we have reference sheets for formulas, for example the circumference of a circle? Because you need that formula to answer #23. (Test 1, 8th grade).
I am confused on the scattergram (#36 test 1 8th grade) Is it supposed to show a trend, but not a straight line?
#38 (test 1)is confusing. Does it include flipping the shapes? Is there a mathematical equation for that? All I can think of is drawing a tree or writing out the combos.
These are ALL excellent questions... and you'll need to know these for the Algebra EOC test as well. You WILL have a formula reference sheet (you can print it off of MathChamber) for the ASK test, you WILL NOT have a reference sheet for the Algebra EOC.
I'll try to answer some of your questions here... for help on various data plots and graphs, cut-and-paste this link and scroll down to Chapter 12 and I think you'll see some helpful video tutors... (I think you'll have to cut-and-paste the link)
#5 requires a little thinking... I'm gonna let you struggle with it awhile longer.
#22 is simply asking you the number of cubes (including the "assumed" hidden ones) are in the figure, yes?
We will have a brief demonstration of cones and pyramids in class tomorrow!!
I agree, Julia, #36 is a crummy question for a variety of reasons... that said, of the answer choices, there is only one that is reasonable.
As for #38, you identified another stinky question!! They should have specified "without transforming the shapes" so please assume that they did.
The hypotenuse is the long side (opposite the right angle) of a right triangle. It's actually our VERY NEXT LESSON!!!. Fyi... the sides adjacent to the right angle are called the "legs."
For #47, you algebraticians s/b able to set up a linear equation with a funky "rate of change" (aka slope, right?) of 42 pounds per 31 days, yes?
Keep the questions coming... it's almost past my bedtime, but I'll look at them tomorrow morning before class.
I sent you specific links up above, but YOU should be able to access the Pearson BLUE ICON on MathChamber and find/access other topics on your own (what am I anyway? your personal math servant?!).
... and for #47, there is no reason that intuitive brilliant young math students such as yourselves couldn't simply estimate an answer... if you started with a 100-lb bag how long would it last at a rate of 42 lbs/month?? There is only one reasonable answer choice, yes?
what are matrix? I found it on #35 test 1 (8th grade)
ReplyDeleteI don't understand #5 Test 1 8th Grade.
ReplyDeleteI don't know how to answer #22 Test 1 8th Grade.

ReplyDeleteHow do you find the volume of a pyramid? (#26, Test 1, 8th grade)
ReplyDeleteI agree with Julian.. Matrix??
ReplyDeleteScattergram is the same thing as a scatter plot, right?? (#36, Test 1, 8th Grade)
ReplyDeleteAnd what is a "Box and Whisker" plot?
ReplyDelete#37, Test 1, 8th Grade
How could you figure out #38?

What is a hypotenuse?(#17 test 2)
How do you solve #47?
ReplyDelete(Test 1, Grade 8)

... and here is a quick tutorial on matrices (matrix addition and subtraction is all you will need to know).

We'll go over as much as we can in class... please don't over-stress for this test, yuzel all do just fine. A little stress is healthy, though!
Okay!

btw, if you go to the MathChamber ASK Prep page, the reference sheets are printable from the upper right hand corner
