May 18/2006 Scribe notes

For the last couple of days in math, we have been learning about patterns, graphs and algebraic formulas.

an example of what we have done is...

Jennifer's problem
Jennifer decides to open up a bank account. She starts off with $30.00 in her account. At the end of each month she deposits $18.00. How much will she have after 1 year?

To solve this problem we must first know how much she starts off with( $30.00) thenn how much she puts in each month($18.00)and finally how long will she be putting money in her bank account( 1 year)


We start off by creating an algebraic formula:



to get the answer we multiply 12( 1 year) to 18(how much she is depositing) then we add the 30 dollars she has now to give us a total of $246.00 in her bank account.

for people who do not know what a variable is it is a unknown quantity.


Then after we did the back of the worksheet Mr.Reece gave to us which said "pattern graFun" at the top.

One of the questions that was on the sheet was this question. It asks you to make an algebraic formula, draw the next shape and graph the information.



The question is:

Tile Pattern. Draw the next two figures in the pattern of tiles shown above. Show how the number of gray tiles varies with the number of white tiles.

The two next figures have been already done for you. The tiles start off with a 3 by 3 box meaning that it has 9 tiles. The middle tile is white(1) then the rest are gray(8). The next box is now a 4 by 3 square which means that it now has 12 tiles. The two middle tiles are white and the remaining 10 tiles are gray. In this pattern the top and bottom rows increase by one starting off with 3. Then the white tiles increase by 1 starting from 1. Then we created a t-chart to show what found out. After, we graphed our information.

How many gray tiles would be needed for 10 white tiles.

There will be 32 gray tiles in the tenth figure. There will be 32 because in the figure that has 5 white tiles has 16 gray tiles. So if the figure with the 10 white squares is double the one with the 5 white tiles it will then has 32 gray tiles.

This worksheet containing 3 different questions will be due tomorrow, may19th/06, 4th period

After we completed that we started another worksheet that had the same kind of questions on it. That worksheet will be due at the same time as the other worksheet.

We have also started something new in class. We have started something called the growing post. The growing post is worth at least 30% of your grade. The growing post is sheets of paper with different question having to do with what we have been learing in class. The will be assigned ever monday and due the next monday. You have one week to complete it. You can either do it on blogger or Hand it in on paper with all the pictures and explanations.

Homework:

-worksheet pattern grafun
-worksheet patterns 1 problem solving -short snappers
-the growing post for the week of may 15 th to 20th due tuesday ma 23rd

No school this monday due to victoria day -jaymie-
