consider this a virtual high five

Today in class, in addition to having some fun with a card trick, we further developed strategies to create number puzzles. Remember, by Wednesday, 31 October, you are responsible for posting a 7+ step number puzzle. And no - "pick a number" does not count as the first step! The blog is a great place to trouble shoot and bounce ideas off of one another. You want to make sure that your puzzle works for any number by the time I check it on Wednesday afternoon. I am sure that your classmates can let you know how successful your puzzle is :)

You will be doing some independent learning and review while I am gone. I will still be accessing my e-mail and the blog, so please contact me if you have any questions! Also, I am still waiting to schedule meetings with some of you regarding the most recent quiz. Do not miss the opportunity to review with me! You will have a quiz on Wednesday, 31 October on sections 2.1 through 2.4. You will have second chance to demonstrate your understanding of the first two sections on this quiz!

I look forward to seeing the thorough work you are doing on your lesson master tomorrow morning.

hey guys.....
i have a question on teh science homework, but it has to do wiht math! You know how we are doing powers of ten, i need help on 12 c. I understand how to do it for like 100, 100... but i need help when it comes to numbers lik 5269.


** Ms. Hogan, we are doing powers of ten. Such as 1000 = 10^3. But i dont know how to do that for numbers such as 5289.

Hi Ms. Hogan.
This is Caroline. I’m here, Saturday night doing my math homework. I am working very diligently. When we are finding opposite sums: ex: -(a + b), why do we have to go through all of these steps instead of just “ finding the opposite”. We could just write out
-a + b then write it as –a – b. Why do we have to go through of all of those steps?

I am glad to see some of you on the blog, and I am glad to see you are such a diligent student (although I do hope you are having some fun!).

To answer your question, if I understand it correctly, we have to go through all of these steps so that we understand the process and can see how -(a+b)= -a-b. Eventually we will reach the point where we can write -(a+b) on one line and -a-b on the next. We've got to walk before we can run. :)

I am glad you figured out #11. You go, girl!

How are the number puzzles coming?

rt said...

well....my number puzzle is coming..slowly. But when i get 1st draft done i will post it so that you guys can give me some tips!

On the quiz, if we just write for example: -(a+b) and don't show the steps will we loose credit?
