Prisms

This stick out from the house has two triangular prisms in it.

All about January. 5 !!!

Due For Tomorrow!- On dotted graph paper we were asked to draw the figure on page 166 then on page 168 do Communicate The Idea along with 3 A, B, OR C, 4, 5, 6, 7 and 8.



SA Challenge- we were asked to take or find a picture on the internet that was either a rectangular prism, triangular prism or a cylinder and post it. to add a picture to the post first click on New Post, add a tittle then above there is a bar with font, bold, italic and so one, near the end is a little picture of mountains, click on it then click on brows and find your picture. For the label put SA Challenge.Due day is Thursday, Jan. 7




Math Text Book- there is now a way to get the math text book from the blog. First find all the labels and there is a link called Grade 8 math text book, if you click on that it will take you to the wed site.

ELA-This month our school is having a spelling bee so were starting, Spelling Book H Lesson one D,E,F,J and H due for Thursday. Also we are going to redo our scenes from the book our group read and show it to Mr. Wilson's class so remember to bring your costumes!!!!

Cube

this is every one's favorit toy the rubik's it is also one of the most basic 3D shape a cube

Rectangular Prism

This is the Apple Store in New York. The store is underground, but the entrance is a glass rectangular prism aboveground.

Twin Towers... Of Cylinders??

This is a picture of two sky scrapers. They are both cylinder shaped!

Cylinder

Can you guess where the cylinder is?

The Pyramid of Giza

These are triangular prisms at the Pyramids in Egypt.

Surface Area

Today in math class Mr.O handed back our quiz and test that we wrote before the break. We then corrected our test and question number 17 was a hard one! We got a sheet for a review of what we did before the break. We then corrected it.


Next we started on the new unit which was surface area.

To determine a 3-D object you have to look and count its faces, vertices (corners,points), and edges. The flat area on a cube is called the face. As you can see on this cube, the yellow, green, and blue area are the faces. There would be 6 faces on this cube.

The vertex is a point on a cube where 3 or more edges meet. In this picture there are 8 vertices because there are 4 on the top and 4 on the bottom.

An edge is the line where 2 faces come together. So in the picture you can see a red face and a green face so one edge is between those 2 faces. There would be a total of 12 edges.

We also went through how to draw images from a top, front, and side view of an image. It is easier to draw these views using isometric dot paper.

E.L.A

The homework in E.L.A is to put your layerd assignments at home onto epearl. Also to start bringing in your costumes for your group skit on Thursday.

Surface Area Challenge

Today in class we re-introduced the concept of Surface Area.

Your challenge is to find a image or photo, either on the internet, or from a picture you have taken (remember - no faces allowed!) that shows:

a real life example of either a rectangular prism, a triangular prism, or a cylinder.

ONCE YOU DO:

1. upload that picture, along with a short caption explaining what the prism or cylinder is, to the blog

2. Make an appropriate title for the post

3. Label the post: SA Challenge, growing post

DUE DATE: THURSDAY, JAN. 7

Changing of the blog

There are some changes to this blog to start off 2010.

First off:

- I added a link to the online textbook that we are using in Math class. This way students can use the blog to find out what homework they missed (and how to do it) and then click on that link if the homework involves work from the textbook. (The links section can be found in the column on the right side, near the bottom.)

- The blog has changed from a Math only blog to a blog that is extension of all of Mr. O's classes. Since there is more than Math going on in Room 107, there will be more than Math going on to the "new" blog. (As a sidenote, the web address will remain 107mathblog.blogspot.com.) To reflect this change, note the change of title at the top of the blog.

Recharging...back in the 2010!!

Hello everyone,

It has been a crazy last few weeks. We have had a lot going on, and a lot of computer problems at school as of late, so we have taken a brief hiatus from the blog.

Not to worry though. We will be up and running once again in the New Year with lots of great improvements...

- SmartBoard Lessons attached
- more scribes
- more videos
- possibly a Math chat room
- and much more.

For now, check out our latest widget...on the left side...a live traffic widget that tracks where visitors to our blog are viewing from. If you'd like to add this widget to your blog, simply go to the Feedjit website and away you go!

Anyhow, for now, that's it. Have a happy holiday season, and Merry Christmas!

Correction$ and Reminder!!!_

We corrected our homework witch was 4-5-9 and 10 on page 128.

We used mytextbook.ca witch is an online textbook, you can use this website if you forget your textbook at school.

we talked about percents over 100% and less than 1%. we also talked about examples in life were theses percents are used in.

Near the end of the class we had to do a practice test on representing percents and it was for homework for the next day. the very last thing to do was to make sure that our math test was signed by our parent or guardian and returned

this class we corrected our homework witch was 4-5-9 and 10 on page 128. we used my text book.ca witch is an online text book on the Internet. we talked about %'s (percents) over 100% and less than 1% that could be found in every day life. near the end of class we had to do a practice worksheet on representing percents, and it was for homework for the next day. the very last thing we did was to make sure that we had our math test signed by our parent or guardian and returned.,.,.,

Representing percents

Today in math class we had three goals but we only got 2 done.

1. Start Chapter 4 Representing Precents.

We learned how to represent percents more than 100%.

We also learned how to represent percents less than 1 ex. 1/2%

2. We corrected the math test! The class average was 75%. Which I think is pretty good.

People had the most trouble with number 22, 23, 24, and 25

Question

Hey O was up um i have a question :(

How do you find if it's a right triangle

My Foggiest Moment

The thing I was having trouble with was finding the whole number in between a certain square root. I now understand it though. Ex. finding the whole number in between the square roots of 8 and 9. The numbers would be 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, and 80.
