MFM2P - Tuesday

Today we took up your tests for Trigonometry. Overall I'm pretty happy. Math help netted some results. Today we also talked about converting Imperial Measure to Metric Measure. Remember, because the United States is our largest trading partner, and so much of what we do in Canada is still in inperial units, a 4x8 sheet of plywood for example, it is so important to know and understand the system. It is equally important though, that we know how to convert between the two systems. Metric is easy because everything is a unit of 10. Many of you did not have your assigned homework done from yesterday, so it is for homework tonight, as well as the first 10 questions of today's handout. That means there are 20 questions that need to be done for homework for tomorrow. You had 26 min of class to do your work today, so there is no real reason why your work should not be done.

See you tomorrow.

MFM2P - Monday

Hi Everybody,

Today we started the unit on Measurement and completed a worksheet in Imperial Measure. The United States, Canada's largest trading partner uses the Imperial measurement system and thus it is prudent to know and understand their system to be effective business people. You need to have up to question 10 done for tomorrow.

MFM 2D - Completing the square

Today I showed you a video that had a nice detailed explanation about completing the square. Here is the link if you would like to watch it again. Click Here.

I have also attached the notebook file from period 2 as an image.

This is my first image upload. So let's see how this goes.

We will be having our unit test on Quadratic equations Wednesday April 29,2009

MPM 1D - Test day!!

I'm sure you are very excited for our math test today! Many of you have been working VERY hard to make sure you understand algebra and have shown me you can stay up-to-date on all homework assigned.
I will mark the tests as soon as I can so we can start into a new unit.
Good luck!

MFM2P

Test Thursday!
Don't forget you have a test on Thursday regarding similar triangles, and trigonometry concerning right angle triangles. Hopefully you all picked up a practice test, that were made available in class, and after school on Tuesday. If not, you can do the practice questions on page 285. The test isn't hard, and you'll have the whole period to do the test. It was good to see many of you in Math Help on Tuesday. That tells me, you want to pass. So.... Remember to bring your CALCULATOR!!! Like you are supposed to everyday! Good luck.

Grade 9 - Bonus question

Today we did Mathematical modeling with graphs. Working with your assigned partner you were to complete Pg. 292 #1,2,3 and then use this method to solve "Another pecan-peanut problem" and "Candy Problem" on pg. 282.
for homework.
Complete #17,18,19(bonus**!!!)pg. 299
You must have #17,18 complete in order for 19 to count as bonus. Do not forget FULL solutions.
Good luck. Have a great weekend!!

Grade 10 - Academic

Rules for Factoring Trinomials (ax^2 + bx = c)
1) Common factor first if possible
2) If both 'a'and 'c' are easy to find the factors (ie. can only multiply 1 way do trialand error.)
3) Decomposition
4) Pull out any common factors if possible.
pg. 244-245 #9-11,14
Try your best!

Grade 9 - Podcasts Uploaded

Grade 9's
I am so proud of your work. We (including me) started this project with minimal working knowledge of the Mac computers. I think you all pulled off pretty good podcasts.

Enjoy! Don't forget to show your parents your creativity in math class. I hope we will be able to do these again soon.

Grade 10 Applied Math

Today was a fun day doing some Anchor charts for Similar Triangles.

Remember some basic facts.
The interior angles of every triangle always = 180`
When two angles in two triangles are the same, then the triangles have to be similar, by the AA method. And that if all sides between two triangles share the same ratio, then the triangles are also similar by the SSS method.

We finished today's class with a note on How to Find the Sides in a Similar Triangle.

For example if /\ <- Triangle

if /\ABC and /\DEF are similar and AC=12 and AB=X, and DF=8 and DE = 4. What would be the length of side AB?
x/4 = 12/8
8x=48
x=48/8
x=6

Remember, lastly, the rules regarding Angles and their patterns when talking about parallel lines. (z patter, c pattern, f pattern, and x pattern) The patterns are important.

Grade 10 Applied Math

Hello, to all parents.

For the next unit Mrs. Gascho and I have switched. I'll endeavor to post the work for the 2P math class here as she did so you can stay informed.

Properties of Similar Triangles

Similar Triangles means that the triangles have the same shape, but not the same size.

There are 2 ways to determine if triangles are similar, 1) Either Angle Angle (AA) method, or 2) Side Side Side (SSS) method. Remember the symbol to say two triangles are similar is ~ -> so ABC~DEF

Classwork/Homework Pg 235 #2,3,5,6,7
Many of you worked well, lets keep that up. Others of you need to remember to stay on task. The more work you get done in class the less homework there is right?! Always remember that you'll have at least 20min of every class to do your work, so don't waste precious time!

See you tomorrow.
Mr. Denys

Grade 10 - Factoring Simple Trinomials

Find two numbers that multiply together to give you the last term and add together to give you the middle term.
If the last term is '+' then the two factors have matching signs, otherwise they do not match.
If the two brackets do not match then the final desired sign goes with the larger number.
Check teachers' note

Grade 9 - Solve for x cont'd

Solving Equations.
When solving equations simplify each side of before applying the same operation on each side. (In other words, crossing the equals sign and switching the operation)
You can simplify by;
a)combining like terms
b) using the distributive law, or
c) eliminating the denominator

Many examples done in class.
pg. 275 -276
#1,3,4,5,7,9

Grade 10 - Academic (Multiplying Two Binomials)

Multiplying two binomials can be done with one of 3 different methods.
Method 1: FOIL (F-first, O-outside, I-inside, L-last).
Method 2: Chart Method (can't seem to copy a chart to paste it here) place the two factors along the top and along the left side. Multiply each term and place it inside the box.
Collect like terms. Always leave your answer simplified in lowest terms.
Method 3: Algebra tiles (as modeled in class)

Grade 9 - Solve for x

Yesterday we did a note to solve for x. Example: 3x - 17 = 28 and 4 - 5k = 8 + k

5t = 25

Pg. 269 1acegik, 2aceg, 8acegik, 10acegik

Today we did word problems involving forming an equation.
It is crucial to start with "let" statements to indicate what your variables stand for. Example in class:
We are getting married and deciding how many guests to invite. We have two venues as options; 1 charges 650 for the hall rental and 32 per person. The other charges 850 and 52 per person. We think things over and decide if we go with option 1 we will invite all 90 family members and a selected list of 62 if we go for the second classier option.
Create the two equations and solve for the total cost. Explain which hall you would chose.
a) Let C be the total cost
Let n be the number of guests.

C=650 + 32n (Option 1) C = 850 + 52n (Option 2)
Sub in n = 90 Sub in n = 62
C = 650 + 32(90) C = 850 + 52(62)
C = 650 + 2880 C = 850 + 3224
C = 3530 C = 4074

Therefore, we will choose option 1 as it is both cheaper and we can invite ALL the family ;)
