### Scribe for Tuesday September 29 2009

Tuesday, September 29, 2009
Hi, 9-05! Today we had a bit of homework, which was to study for our test on Thursday, to accept the blog authorship and to write in your journal (which you should be doing daily).

In class we were using 3D shapes (i.e cube, rectangular prism, isosceles triangular prism, etc.) and counted the lines of symmetry. When you are counting the lines of symmetry of a 3D object you have to count the lines as if they're like saws cutting through the object. You can see the equality better that way. This is plane of symmetry. When you're looking for lines of symmetry, it's easier to look for two faces that are parallel to eachother.

Towards the end of class we discussed nets of rectangles and cubes. We were given graph paper and were instructed to make a 2x2 cube and a 3x2x1 rectangle. We found that 6s² is the most elegant algebraic expression for surface area of a cube. You multiply 6 by one side (currently represented as s), and you square that because cubes are equal all around. We didn't have enough time to confirm what the proper algebraic expression is for a rectangle, so hopefully we will by tomorrow! :P

Remember ...
Tessellation means tiling, having to do with patterns.
The corner of a shape or figure is called a vertex.
... to study for the test :)

Feel free to comment if I've missed anything. Good luck everyone!

xtian 9-05 said...

thanks !

xtian 9-05 said...

Hey Whats our home work today except for the math journal and test?

linda 9-05 said...

That was it, I think. Unless you didn't hand in maps or reading response for L.A., or have anything for art/music.

linda 9-05 said...

Oh, and to study for the mapping test on Thursday.

kara 9-05 said...

Hey thanks Linda, now I'm all caught up for class!

Karen9-05 said...

thanks linda ! and you did a great job. i think you got everything that needs to be there and more ! keep up the good work. and is that all the homework in math, journal and study for test? thanks again (;

Zerlina905 said...

Great blog post Linda. I think you covered everything in class. Maybe you should have added color to some of the words of seperate the words and the definition with colour. Or some colour when you used mathimatical terms such as the different shapes. But overall everything is great like the picture of the net of the cube (:

angela9-05 said...

You did a great job Linda. Though, like Zerlina said, you should have put more color in. To make it look more interesting. Also, I think you spelled "algebraic" wrong. But, over all, you did great! :D

Mr. H said...

Abby905 said...

Great job on the scribe post Linda! Thanks for putting that 6s2 is the most elegant algebraeic expression in your post! I didn't catch that in class.. ^.^

Dean 9-05 said...

LINDA!
great scribe to start off the year!
i loved your use of vocabulary and how deeply you explained things.
Thanks for reminding me for the test, which i should be studying for.

One little thing i caught in the scribe however. I think when you find the area of a cube, you should be multiplying 6 by the area of a side. What you put is to multiply 6 by the side length. Pretty sure that's what it is, but then again i could always be wrong! Everything else is perfect!

Thanks Linda!

Mr. B. said...

Yes Mr. B is impressed. I hope everyone gets a chance to continue to comment.

shaneille 9-05 said...
