Kim's Math Journal Entry

Todayin room 5 for math, we went on the website http://www.mymathplayground.com(that/ I didn't go on due to somethings... >.>) and played rescue the zongs.


Just by doing it you can learn A LOT!


For example:























I learned that if the line is vertical like the y axis, it is an "x" line and if it's a horizontal line like the x axis. then it is a "Y" line.



I also learned that you can make a chart to find out the answer.



For example:

We went over some questions in math class. Different colours indicate different questions

Today we went over the assigned homework, which one of the questions were number 17, on page 197 in the textbook. The "Addition Pyramid." At first I was confused, but the more we discussed it as a class, the more I understood. It's all about "combining like terms."
Here's the question:

17. Complete the addition pyramid. Find the value in any box by adding the expressions in the two boxes immediately below it.





Do you get the pattern?
So ...
first the pinkish purplish:
2x-1+x+3
= 3x+2

second the dark green:
3x-2+x+2
= 4x

third both of them combined:
x+3+3x-2
= 4x+1



That's all for my journal entry. Thanks for reading (:

Today in math we learned how to divide polynomials using algebra tiles.
Then we were given another question about dividing polynomials, It was about a cylinder and what the ratio of the Surface area to the radius was.



To figure out this question you need to know the formula for a cylinder.

The formula is:



At the end of class class we were given homework to do. While we were working Mr. B told us what he wanted in our stash its.
