Scribepost for May 12

Today in Math class Mr. P wasn't here so Mr. Isfeld is teaching us. There was also an assembly about foot ball so we didn't do much.

But what we did do is study for our test tomorrow.

Here are some things to know to be ready for the test.


This means diameter equals radius x 2.

This basically means that the diameter is twice the radius.


This is the formula to find out the circumference. The formula stands for Circumference equals Pi times diameter

This means that the diameter times the Pi will give you a circumference.

The Pi is 3.14159265

But for the test, we will use the shortened version-3.14.


This is
basically the first two formulas combined. You multiply the radius by 2 and multiply it by π (3.14)

And we also got a study quiz.

This is what it looked like:

Diameter Check Radius

The middle "check" part is for you to check your answers later to see if you got the answers right.

You can also do this in home without the sheet.

I hope every passes the test.

Edit: I keep forgetting, I pick Brayden to do the next scribepost.

Scribe post for May 7 2009

Today in math we did more things about circles.

Today we also got a new seating plan. Instead of our normal rows we were put in groups.

We started out with a warm up question. The question was how can u start from the centre and draw a circle without lifting your hand. While we were working on his we had a homework check for the problem of the week.

The answer to the question was start from the centre and fold the corner then start drawing over it. The once you start turning unfold the corner and finish the circle.

After we finished with the warm up question we checked our problem of the week. The problem of the week question was using the numbers 2/7, 4/7, 6/7, 8/7, 10/7, 12/7, 14/7, 16/7, and 18/7 only once, place them in the circles such that the sum on each side is 34/7.The answer was starting from the top going right: 4/7, 10/, 14/7, 6/7, 8/7, 18/7, 2/7, 16/7, 12/7, 4/7.

Note: This is not the only answer to the problem of the week.

After we finished checking our problem of the week we moved on to a group activity. The activity was everyone in your new seating plan were to measure a bunch of circles and put down their findings on a chart that was with their math notes.

After some time working on this activity we reviewed our answers. After that we had some notes.

We have discovered that the circumference or perimeter of a circle is approximately 3 times its diameter. Therefore we can use 3 x d when estimating circumference

We have also discoverd that the ratio of the circumference to diameter is approxemetly 3.14. We can use this value to calculate circumference. This value is repersented by a constant Pi which is often repessented by the greek symbol ---------------------------->

After we finished the notes we all handed in our homework which was to make a illusion with a circle that was at least 20 cm in diameter.

The next person I choose for the scribe post is Brendan.

This is what we did in Math on April 20, 2009

Problem of the Week:

What is the least positive integer meeting each of the following conditions?

Dividing by 7 gives a remainder of 4.
Dividing by 8 gives a remainder of 5.
Dividing by 9 gives a remainder of 6.


Integer Subtraction using chips

In pairs solve the following using (+) and (-) chips.

(+9) - (-8)= -1
(-10)-(-4)= -6
(+5)-(+8)= -3
(-3)-(-7)= -4
0 -(+6)= -6

To subtract integers using chips (+) and(-) chips...

1. Model the first integer in the equation by using chips.
2. Then take away the number of chips indicated by the second integer.
3. "If nothing is there add a zero pair."

Note that adding zero pairs to the first integer does not change its value but does give something to take away if we need to in order to solve the question.

Here is an example:

5-7= (+)(+)(+)(+)(+) then add (+)(+)
5-7= (-)(-)

5-7= -2

And then we played a game where we had to go up/down the mountain/bottom of the sea then back to sea level.

And we got back our tests from Friday.

Math Class For April 6th

For April 6th 2009's math class, the substitute teacher took time in explaining with us the basic introduction to "Integers". So for anyone who was
n't there , or who was there but didn't quite get the notes. "Keep On Reading (:"

The word
"Integer" literally means untouched or
whole in Latin. Integers from the set of "all whole positive and negative numbers and zero".


- Positive Integers : Numbers greater than zero

- Negative Integers : Numbers less than zero

Integers are written with a
"positive or negative"
sign in front of the number. eg. - (+1), (-1), +1, -1


positive numbers are written without the (+) .
eg. - +1 can be written as "1"

The sign of
a integer indicates its position relative so zero. eg. of a numbers on a "Cartesian Plane"eg. - 2,2 (q1) , -2,2 (q2) , -2,-2 (q3) , 2,-2 (q4)

Opposite Integers

Every integer has a negative counterpart, when these are added together .. they have a sum of zero. The pairing of opposite integers are also known as
" zero pair".

eg. -
(+1) + (-1) =0

That's The End Of The Note Taking Parts ..

but work wasn't over yet ..

We were all given worksheets about "Integers" with the exceptions of the people who weren't there. If ever you didn't happen to finish it in class, remember that it IS homework.

comments , THANK YOU ! .

watch this ! (:

The first thing we did today was number of the day, as usual.
The number was 8756.934, in case you weren't there today, or you
didn't write it down.

After number of the day, we did 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 90° 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 of pt. (point) A draw an arc.
c) Place compass on pt. B draw an arc.
d) Use a ruler to connect the intersections of the arcs that line is a perpendicular bisector.

Angles -
angle - the figure formed by two lines with a common end point called a vertex.

acute angle - less than 90°

obtuse angle - more than 90°
less than 180°

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 pt. S (intersection of line and arc)
c) Arc from pt. T (intersection of line and arc)
d) Line from arc intersection to vertex.

After we did those notes, we worked on some Math Links.
Pg. 116 - 121.

Thank you for reading my scribe, and please comment after, if I made any mistakes, or errors.
I choose JORDAN for the next scribe.

P.S : Sorry my scribe was a little late, my computer kept shutting down.

Today in math we did number of the day which was 1936.295. Number of the day is always homework! We had homework and notes:

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

eg: 4 cm squared
4- amount cm- units

Area of rectangle or square

Length x width = area

a=L x W
a=6 x 2
a= 12 m squared


Parallelogram= a four sided figure with opposite sides parallel and equal in legth.

I means sides are equal in length
^ means lines are parallel

base= a side of a two dimensional closed figure
=common symbol is b.

height= the perpendicular distance from the base to the opposite side.
=common symbol is h.

Perpendicular= a line that meets another line at a right or 90 degree angle.

a= L x W a= b x h
a= 6 x 2 a= 6 x 3
a= 12 m squared a= 12 m squared

EEach height is the exact same size.

Area of Parallelogram
a= b x h

h= 3 cm a= b xh
b= 9 cm a= 9 x 3
a= 27 cm squared

Find the area of the following figures.

scribepost for march 5

today in math we did number of the day. The number was 9965.267 you and if did not finish it it was homework as always.

after that we did our test on probability since it was Thursday.
if you finished the test before it was time you had to do this:

we did not get to go over it.

after we did the test we went over it and then we went over the homework from yesterday.

then Mr. Isfeld gave us a question to do:

what is the probability of landing a coin on heads and rolling a 3 with a normal die
to find the answer you need a:
probability tree/diagram
/ / / / / / /
1 2 3 4 5 6
/ / / / / /
1 2 3 4 5 6
p(H and 3)= favourable outcomes/possible outcomes
p(H and 3)=1/12 or 1:12 or 8.3%
what is the probability of rolling a 2 on 1 die and drawing the out of a bag containing the letters S N O W
FIND 72% OF 120

Scribe Post for March 4, 2009

Today in Class we did number of the day. The number is 7791.692.
Remember it's for homework everyday !

Then we continued on our Probability notes.

Outcome- is the possible result of a probability experiment.

Favourable outcome- is a succesful result in a probability experiment.


The tiles S, N, O, W are placed in a bag.

1. What is the probability of drawing a letter "W" from the bag?
Another way to write the same question is P(W).

P(W) = Favourable outcomes
Possible Outcomes

= 1/4 (fraction)

= 25% (percent)
= 1:4 (ratio)

2. P(S or O) = favourable


= 2/4 - 1/2

= 50%
= 1:2

3. P(consonant) = favourable


= 3/4
= 75%
= 3:4

4. P(B) = favourable


= 0/4

= 0%

A bag contains 10 marbles, show the probability of the following event as a fraction, percent and ratio.

a. P(red marbles) = 6/10 - 3/5
= 60%
= 3:5

b. P(red, blue or green marbles) = 10/10 - 1/1

c. P(not a red marble) = 4/10 - 2/5
= 40%
= 2:5

The letters M, O, U, N, T, A, I, N are in a bag.
a. P(N) = 2/8 - 1/4
= 25%
= 1:4

b. P(consonant) = 4/8 - 1/2
= 50%
= 1:2

c. P(letter) = 8/8 - 1/1
= 100%
= 1:1

What is the probability of flipping a coin heads and rolling a 6 ?

Dont Forget: Please comment on what i did bad or good.

Scribe Post for March 2, 2009.

First thing we did in class, was do number of the day. The number today was 9876.123.

- the likelihood or change of an event occurring.
  • Favorable Outcomes -> what we want to happen.
  • Possible Outcomes -> what might happen.
Probability can be expressed as a:
Then, we had to come up with:

one impossible outcome/event.
eg. for a pig being about to fly.

one certain outcome/event.
eg. having math homework.

one not sure of outcome/event.
eg. the weather tomorrow.

Right after, we had to do this little problem. We had to place the letters above the percent, fractions and decimals to see how likely that event will happen.

a) Flipping a coin and
landing on heads.
b) With one normal six sided die you roll on 8.
c) A boy contains 8 red markers. You reach into the bag and pull out 1 red marker.
d) You spin a spinner with 4 equal sections marked chocolate, fruit, yogurt, and ice cream. What is the probability of the pointer stopping at fruit?
e) A bag contains letters A, B, C, D, E, F, G, H. You pull out a H.
f) A bag has 3 gold marbles and 1 silver marble. You pull out silver marble.
g) The next baby born in Winnipeg is a boy.

Today in Math class we did Number of the Day, if you weren't here or you forgot to write it down the number was 2691.543. This is homework everyday. Sometimes in number of the day we divide, multiply or sometimes even make fractions often using the digits from the number of the day.

Then we continued our Math Links on pages 398- 401. A reminder that our quiz tomorrow( It's a Thursday, there's no surprise) is going to have similar questions to these pages. Mr. Isfeld said it would be fine if I only gave examples, instead of every single question.

Here are some examples:

Draw a balance to show the equation 12=3+M, if M represents an unknown mass.

B) What total mass should be on each side of the balance?

C) Solve the equation to determine the unknown mass.

These aren't in order, they're only EXAMPLES!!!

The average life span of a grizzly bear is 25 years. This is 15 more years than the average life span of a cougar.

A)What equation will model this situation?

B) What is the average life span of a cougar?

At the Commonwealth Games in Australia, Canada won 86 medals. This was 24 fewer medals than England won.

A) Write an equation to model this situation.

B) How many medals did England win?

Today in class, we did our number of the day. Just in case you were away, the number was 6918.205. Make sure you finish it everyday. 

Mr. Isfeld showed us the correct answers from our test yesterday. 


     a+5=11                        a+5=11
 a+5-5=11-5                    6+5=11
         a=6                            11=11

     b-3=7                          b-3=7
b-3+3=7-3                    10-3=7
         b= 10                          7=7

    c / 5 = 25               
5 x c/5 = 25 x 5

    6d/6=30/6                   6d=30
           d=5                       6(5)=30

    7e+8=29                   7e+8=29
7e+8-8=29-8            7(3)+8=29
     7e/7=21/7               21+8=29
           e=3                         29=29

      2f-2=8                           2f-2=8
 2f-2+2=8+2                  2(5)-2=8
     2f/2=10/2                    10-2=8
           f=5                                8=8

    g/3+2=7                     g/3+2=7
g/3+2-2=7-2                15/3+2=7                       
         g/3=5                         5+2=7                    
     g/3x3=5x3                         7=7

     h/4-3=2                h/4-3=2   
h/4-3+3=2+3         20/4-3=2
         h/4=5                     5-3=2
     h/4x4=5x4                    2=2
4x+2+3x=9               4x+2+3x=9
       7x+2=9          4(1)+2+3(1)=9
    7x+2-2=9-2               4+2+3=9
        7x/7=7/7                    6+3=9
              x=1                             9=9

Then Mr. Isfeld gave us a word problem. The problem was the following question:

There are 2 more than half as many boys in class as girls.  If there are 12 girls, how many boys are there?

The solution to this problem is:

6x2+2=d              6x2+2=d                                                There are 18 boys in class.
   12+2=d              6x2+2=14
        14=d                12+2=14

After that, Mr. Isfeld gave us a question right at the end of class and we had to do it. 

So here is the answer. 

6 + 4 / 2 - 4 x 2 =

Mr. Isfeld gave us the answers for the balancing act.

Today in math, we started with the number of the day. Just in case you were away, or did not write down the number of the day, the number was 5214.897. It's very important to get your number of the days finished, because sometimes you may have to hand it in to go to special events like dances.

Since today was Thursday, we had a math quiz. Because we have math quizzes every Thursday.
On our math quiz, we had linear equations like, a+7=10, d-4=5. We had to solve, and then verify each of the questions. There was a total of 10 questions on the math quiz. We did not get to correct the test in class, so we handed them in to Mr. Isfeld at the end of class.

Also, if anybody in class was done the quiz before class ended, we were given a balancing act to solve. The total weight is 50. Some strategies you can use to solve these questions, is to divide the total weight by 2, so you can make it easier, then at every arm or split, you can divide by 2. Although, this puzzle is more difficult, because there are objects in the way of the arms. If you have not finished this in class, it is homework.

12. Dividing the number by 3.55 and rounding the solved number into the nearest hundredth.
13. Finding the product of all the numbers.
14. List all the prime numbers.

17. Combining the numbers in the ones & tens place to make a two digit number, then writing the prime factors.
20. Writing a fraction using the number in the 1000s place (denominator) and the 10Th's place (numerator).
21. Making a improper fraction using any numbers.
22. Making a mixed fraction using any numbers.
23. Writing the answer for 22 , and expressing it into a decimal.
24. Drawing a picture to represent the answer for 22.
25. Writing the answer for 21 as a % (percent).


The following thing we did was finishing up all the incomplete work (worksheets), from our "Provincial Folders". These worksheets would normally be the recent ones we did. They are ....

Patterns : STEPS ...

a. Construct and extend a pattern.
(make a continuation to the past 1-3 terms)
b. Represent a pattern pictorially.
(make a picture representation of the pattern)
c. Describe the pattern.
(algebraic language)
d. Develop a chart.
(line graph)
e. Make a prediction.
f. Generate Graphs
(interpret, interpolate, extrapolate)
g. Write an "Algebraic Expression" for the pattern.
( 3xt=(n)+1 )
h. Predict "nth" values.

And the rest are pretty simple ...

Understanding Fractions, Mental Math (132/6), Ordering Fractions from Greatest to Least, Matching the Fractions (picture)
to the Symbols, Representing Numbers (Represent one half as many ways as you can.

Finally the homework for today is to solve the following question.

Write an "Algebraic Equation", and solve it for the following statement.
" Daylan talked for 45 minutes in todays class ... what did he do for the rest of the leftover minutes ... "

I choose Joseph to do the next scribepost ....
P.S. Sorry if there were NO pictures, videos and other things, and sorry for the LATE scribepost .

Scribepost for February 9, 2009

Today in math we did number of the day and the number is 8129.693. Don't forget, if you didn't finish it at school, its for homework.

After that, we had notes to copy down and if you weren't there, here they are:

Patterns :
e.g. construct a pattern extending pattern
1 2 3 4 5

Describe the pattern using your own words.

" Each term has the same amount of spaces as the term number.

e.g. 1 space in term 1

" 1st term has 2 vertical lines, each term after that has one additional vertical line. All vertical lines are connected by a horizontal line at the top.

Create a Chart (either)


I believe term 25 will have 151.


Algebraic Expression:

Must work for every term

2 t + 1 = Lines <>
^ ^
Expression Equation

Nth = Means any number.

51 =lines

When we finished that, we worked on our Provincial Folders and it was on Patterns.

I apologize for putting it up late and for not putting any videos or websites.

Thank You for checking out my scribe post.

I choose Jem to do the next scribepost.
Please tell me if I made any mistakes or forgot anything and don't forget to comment.
