HAND-IN

Please be neat and make efficient use of space as we discussed in class; use white space (on paper) where you need it, but don't waste it either!! The Area Model need not be huge to be effective

Sorry to ask, but do we use the area model and/or the method with the arrows? I can't tell.

ReplyDeleteFor now I would like you to use both. It is important that you are comfortable with both methods.

DeleteIs there any extra credit that we can do? Mr C

ReplyDeleteDear j^7,

DeleteIf you are asking how to improve your quiz grade, the best way to do that is to GO BONKERS ON THE CHAPTER 1 TEST... then we can talk.

Are you watching videos? Coming in for extra help? Doing the extra optional assignment I just sent to everyone?????

Then we can talk.

what is procedural algebra

ReplyDeleteI don't know

DeleteI did the optional problems and on number 3 I got the wrong answer. I know what the right answer is and I checked over the work 4 times and could not get the right answer. I got -720 did anyone else get that??

ReplyDeleteThis is my work reply to this if you see what I did wrong.

Congrats to RYAN for catching MY MISTAKE!!

Delete2 points extra credit for you on the next test!!

I knew I would make a mistake somewhere!! Those were hard problems!!!

I forget, how do you make the area model for #36?

ReplyDeleteThanks for asking... however... I'm going to enforce a blogging rule here... I'm not answering a question unless you re-state the problem in your comment.

Deletedid you try looking back in your notes (Hint: it's the rectangles)

ReplyDeleteHow do you do an area model with varibles? like 2x+(-2)?

ReplyDeleteYou are supposed to say "I watched the MathChamber Academy videos labeled section 1-7 yada yada yada and I still don't understand blah blah blah" ... I'm not sure you can say that... did you take the 4mins 47 secs to watch this video?

DeleteI need you to watch and check back with me asap to lmk if it helped...

This is the Level 1 video. That should be enough to help you with your question... for more advanced problems, check out the Level 2 and Level 3 videos... you know how to get to MathChamber Academy, right... just go to MathChamber.com and click on the Academy logo!

Hi mr C, I was just a little mixed up on problem 31 (-84/14). When you divide a negative by a positive, you get a negative, right?

ReplyDeleteDear Mixed Up,

DeleteYes, multiplication and division follow the same rules when it comes to signs.

It's worthy to note that MATH WORKS BACKWARDS AND FORWARDS.

You would likely agree that (-6)(14)=-84, am I right?

Based on this multiplication fact, you should also agree with the following two statements:

a) -84 / -6 = 14

b) -84 / 14 = -6

Finally, think about having 84 negatives in a bag. If you split them up and shared them equally amongst 14 bags, there would be 6 negatives in each bag, right? That's a VISUAL reason why -84 / 14 = -6.

Gotsk it??

Thanks mr C, I gostk it!
