Friday's Math Class




At the start of math class we corrected Thursday's homework. Which was pg 214-215 # 5-12.






Some Definitions






Improper fraction: The numerator is larger than the denominator.






This is an example




Mixed Number: Has a whole number in front of a fraction.




Next we did # 4-5 on pg 220 and corrected it


After that we looked at selina's Wednesday post on January 27.

The dude that jumped off the cliff face

One day there was a dude named Drew .

He decided that he was going to jump off a cliff that was covered 3/4 of the way down with pecking chickens that said moo!!!

The bottom 1/4 of the cliff face was covered in donkeys that kick at people and eat brocolli.

If the DUDE is 8/90 down the 3/4 of the cliff with pecking chickens when he yelled"YAYAya"....

... How far was he down the cliff face?

O: Also how far was the Dude down the total cliff face if he was knocked out by the kicking donkeys 12/79 of the way through that quarter of the cliff face and smothered in mushed up brocolli?

Divide these Fractions!

Today we found how to divide fractions.

P.S. If you click on the image it will make it bigger.

here is an example Question and Answer.

Q) Mark uses 1/3 of a tank of gasoline in a five-day work week driving to work and back. On average, what fraction of a tank does he use for each round trip?

A) 1/3 Divided by 5/1

1/3 multipied by 1/5 = 3/15

Hope that helps a little! HOMEWORK!! Math-Page 208 5-13. E.L.A- book report and spelling chapter 7. ☺

End of the Unit


Math- On Friday we learned how to find the surface area of a cylinder.

To find the surface area of a cylinder you need to know 3 different formulas:

A=pie(3.14)*radius(r)2(squared), A=l*w, A=circumferance*w.


!st Step: draw a net of the cylinder.


2: find the radius of one of the circle so you can find the area of it. To find the area, times the radius by itself and times that by pie. Double this answer to have the surface area of both circles.


3:find the surface area of the rectangle. To do this times the diameter of the circle by pie, times that by the width of the rectangle and you have the surface area.


4:add the answer from step 2 and 3 and you have the surface area of a cylinder.
Homework- Page 186 3,4,5,6,7,8,9,10 if you are done you can start the review.


ELA- We started our rough copies on "What makes a true Friend". Remember to type your good copies on the computer and to double space.

Page 180...and some La~!~


In math today we went over #8 on page 18O...which is to do with triangular prisms.
#8. Paco built a glass greenhouse.

a) How many faces does the greenhouse have?
The green house would have 4, the front and back which are triangles, and the two sides which are rectangles, but it wouldn't be the bottom because if something was dropped the whole thing would shatter.

b) How much glass does Paco need to buy?
...its at the top...but i am suree you can see it.

Homework
Math: Page 180 #5,6,10,11,12.

There wasnt a lot of math today, Only correcting. First thing we did was look at the last blog post and the stuff on the blog. Then went to the homework in the text. Page 168-169 3-8. We didnt really talk about it so we dont have much to say because afte that we kind of just put aside math and the art people worked on their mittens and other did optional things.

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.
