Lesson+14+By+Kyle+and+Cheyenne

Ok, so i **//finally//** got round to it. Happy now Mister? :D Yeehaa,you got it done. Now I'll see how Hannah is getting on.

We started of the lesson with a sort of number pyramid. We got the first three numbers at the bottom and we had to add them together to get the top number. It looked like this when finished: 94 30 64 -21 51 13

But that was just introducing an idea. (i never got what it was introducing during the course of the lesson though.)

Next we did a chart showing a pattern.

__n n+4 (n+2)-1 (n+2)-3__

0 2 1 -1 1 3 2 0 2 4 3 1 3 5 4 2 4 6 5 3

50 52 51 49

We are subtracting one each time so (n+2) - 3 must equal n-1.

After that we had a number tricks and algebra sheet which we had to figure out the algebra too. (Cheyenne was supposed to scan this sheet.)

Then Mr taught us **//"SOME ALGEBRA SKILLS WE NEED!"//**


 * Algebra tricks.**

Writing instructions using letters and symbols. E.G. Think of a letter ---> n Divide by 2 ---> __n__ 2 Multiply by 5 -> __5n__ 2 Add 3 ---> __5n__+3 2


 * Simplifying

E.G. (2n+3)-2 > 2n+1 __4n+6__ --->2n+3 2


 * Expanding

2 (n+3) 3 (2x+1) -2 (x+1) 4 (3x-2)

Our homework for that day was excercises:

21.1 number 1-5 24. 1 number 1-4 25.4 & 25.5 number 1-16

in our orange alpha books.

Argh. Thank god thats over. (: Oh Kyle...it wasn't that bad surely.Anyhow you did a good job.
