Scribe Post for March 25, 2009

Today in Math we did number of the day, 1347.892. Then we were given a Sudoku to complete using the letters... S.P.R.I.N.G.

The first one we were given was Easy,

The next one was supposed to be harder,

The last one was the Hardest,

We had to later correct them...

This is the answer for #1


This is the answer for #2

After we were done we got to play a game with a friend called Isolation, this game is where the players take turns at colouring a hexagon, and you couldn't colour a hexagon that is joined to one that is already coloured. the object of the game was to be the last player to shade in a hexagon.

umm I don't know Kevin I guess
Sorry that i wasnt able to post the answer for Sudoku #3 but i wasnt able to get it written down.

Yesterday in class, we started off with "Number of the Day". The number of the day was 8756.934. Then we took some notes on perpendicular bisector and angle bisector.

Here are the notes:

Bisect: -Bi means "two"

-sect means "cut"

-so bisect means to cut in two

Perpendicular Bisector

A line that divides a line segment in half and is at right angles to it


How can you create or draw a perpendicular bisector?

1. Free hand, o.k. but not perfect

2. Protractor gets us 9o degree angle

-Ruler cuts line in half


3. Use a compass and create arcs

a) Open compass to greater than half the distance of line

b) Place compass on point A, draw an arc

c) Place compass on point B, draw an arc

d) Use a ruler to connect the intersections of the arcs that line is a perpendicular bisector


Angle: the figure formed by two lines with a common endpoint called a vertex


Acute angle: less than 90 degrees


Obtuse angle: more than 90 degrees

- less than 180 degrees


Angle bisector: the line that divides an angle into two equal parts


How do we make an angle bisector?

1. Free hand not perfect not accurate enough

2. Protractor


3. Compass


a) Arc from vertex

b) Arc from point S (intersection of line and arc)

c) Arc from point T (intersection of line and arc)

d) Line from arc intersections to vertex that is your angle bisector

After taking down all the notes, we worked on page 116-121 (Math Links)

BY Devin

On Friday we started with ''number of the day" and the number we did was "4792.831".

After Number of the Day, we did notes on

These are the notes
parrallel-describe lines in the same plane that never cross or intersect
-they are marked using arrows
perpendicular- describes lines that intersect at right angles(ninety degrees)
-they are marked by using a small square

Today in class the number of the day is 1936.295 so you all know that it's homework.

In math class we were taking notes about Area.
So for now I don't even know how to put drawings or pictures in the post so sorry guys.

Now I'm going to tell about area.

Area is the number of square units contained in a two dimensional region

Parallelogram - a four sided figure with opposite sides parallel and equal length

Base - A side of a two dimensional close figure
- common symbol is b

Height - the perpendicular distance from the base to the opposite sides.
- common symbol is h

- A line that meets another line at a right or 90 degree angle.

Those were the notes we have taken.

Here's a video about Volume (L x W x H) oh and if the link ain't working then press ctrl + left click

Scribe Post for March 13, 2009

Today at school we started with the Number of the day. For those who were away the number is 2468.135. Remeber number of the day is ALWAYS homework!

1. Half of the number of the day is:
2. Write the number of the day in expanded form:
3. Write the number of the day in written form:
4. Round the number of the day to the nearest 100:
5. What number is in the tenths place:
6. The number of the day doubled is:
7. Write the number of the day in expanded notation:
8. Write a power using the number in the 100th place as the base and the number in the 10s place as the exponent:
9. Write the above power in factored form:
10. Cube the number in the ones place:
11. Square the number in the hundreds place:
12. Divide the number by 3.55 and round to the nearest hundredth:
13. The product of all the numbers in the number of the day is:
14. List all the prime numbers in number of the day:
15. Write the number of the day in scientific notation:
16. The whole number is divisible by (circle): 2, 3, 4, 5, 6, 8, 9
17. Combine the numbers in the 1s place and the 10s place respectively to make a two digit number and write the prime factors:
20. Write a fraction using the 1000s place as the denominator and the tenths place as the numerator:
21. Use any two numbers to make an improper fraction:
22. Use any of the numbers to make a mixed fraction:
23. Write the answer to number 22 as a decimal:
24. Draw a picture to represent the answer to number 22:
25. Write the answer to number 21 as a percent:

We also took notes on Still More Probability.

Random- an event in which every outcome has an equal chance of occuring.

Experimental probability- the probability of an event occuring based on experiment results.

Theoretical probability- the expected probability of an event occuring.

e.g. flipping a coin
Theoretical probability Experimental probability
5 heads, 5 tails heads 1,6, 5 tails 7, 4, 5
favourable over possible do the experiment

The larger or more trials in an experiment the closer experimental probability gets theoretical probability.

After that we took out our Maths links text book. We worked on page 180 and number 1 to 11.

first we had to do the number of the day.Our number was 1247.936.Then we had a test.The test was about probability stuff.After if we were done the test we had to solve a question.The question was I have 3 pairs of hoodies(black,blue,red) 4 t- shirts, 4 pairs of pants and 3 pairs of shoes.If I wear ! of each. How many different outfits can I wear?
White,Brown,Black. What is the provability I will wear all black?

Probability tree and table

In class today we had to do a tree diagram to solve the answers to Page 168 from 2 to 14. We also kinda learned how to use a table diagram as well.

Here is an example of a tree diagram and a table diagram
