Ch+6+Polynomials!

=Polynomials=

= Chapter Test - Tuesday April 3, 2012 - This chapter has ended and it is time for the chapter test.=

I've seen excellent attempts and work from some in the class. Remember this: A zero is much worse on a test than even 20-50%. Better to give it a try and get a few marks than not try at all.
There will be review on Friday and Monday. Over the weekend please review the videos and homework questions set up on the website on this page and the Ch 6 Polynomials! page. If you have questions please email me!

=Lesson 6.7 Multiplying or Dividing a Polynomial by a Monomial - Wednesday, March 27=

= **BIG IDEA:** Multiply and divide with monomial. =

=Homework Questions for Monday, March 21: Questions: Pg. 320 - 322 Questions 6, 7, 10, 11, 12, Bonus 18, 19=

And your Multiplying Polynomial videos. media type="youtube" key="ssY1dFl7d30?version=3" height="360" width="640"

=Lesson 6.6 Solve Problems Using an Organized List.=

= **BIG IDEA:** Solve Problems involving polynomials using organized lists. = = This video is not math. Just watch it and let me know what you think. It's about why videos go viral. = media type="youtube" key="PPN2BHydH3Y?version=3" height="360" width="640"

=Lesson 6.5 Subtracting Polynomials - Thursday, March 22 and March 23.=

=Quiz was Thursday. You can also write it on Friday. Please contact me by Monday with a reasonable excuse for why you were unable to be in class Thursday or Friday. (You can email me at stephenhadden@nlsd113.net)= = **BIG IDEA:** Subtract Like Terms Using Different Strategies =

I will not lie, this idea takes a bit of work to fully understand. It is harder to get than adding polynomials, but there are some very simple ways to transform these questions into adding polynomial questions. My first and best suggestion is distribution of the negative sign. Watch this video to see what I mean. media type="youtube" key="5ZdxnFspyP8?version=3" height="360" width="640"

=Mid-Chapter Review Continued - Wednesday, March 21. (Supply Teacher)= ==The supply teacher will provide you with a worksheet of three questions to complete in class reviewing the ideas taught so far from Chapter 6. Following that please attempt the questions from the text book pages 299-300. Try at least two or three questions from each Lesson review (so from the 6.1 section, 6.3 and 6.4)==

= **Mid-Chapter Review - Tuesday, March 20.** = ==**No set homework for today. All students have the opportunity to complete and hand in homework questions from any lessons in chapter 6. Wednesday will be the last chance to get homework marks for the first half of the chapter.**==

= **Lesson 6.4 Adding Polynomials** = = **BIG IDEA:** Simplify Polynomial sums = Hint this works in the very same way as gathering like terms.

=Homework Questions for Monday, March 19: Questions: Pg. 294-295 3,4,6,7,8,9 10, 11, Bonus 18=

And videos of Monday's big idea. The second video goes a little beyond the examples in the textbook but do show the ideas that we need to know! (For example: **gathering like terms)** media type="youtube" key="Oe1PKI_6-38?version=3" height="360" width="640"

media type="youtube" key="c0iXgjXt1ZQ?version=3" height="360" width="640" I will provide one **Bonus mark** on your next test if you leave a question or appropriate comment on the discussion board (which does mean you have to register with the website), or provide me with a slip of paper with the answer to this question (and your name) during class this week. What is my favourite movie? Inception.

= **Lesson 6.3 Gathering Like Terms** = = **BIG IDEA:** Simplify Polynomials =

=Homework Questions for Friday March 16: Questions: Pg. 288-289 3,4,5, 12, Bonus 11, 14=

And once again here is a Khan Academy Video on Simplifying Polynomials. Pretty much Friday's lesson in about 3 1/2 minutes. As well, please try out the x-power algebra tiles tool. It can be really helpful to help you simplify polynomials if you have the hang of using the algebra tiles. media type="youtube" key="vN0aL-_vIKM?version=3" height="360" width="640"

=Definitions:= Like Terms: terms of a polynomial that are identical (same variable and same exponent) except for their coefficients; like terms are represented by algebra tiles of the same size. Eg. 3x and -2x are like terms. (taken from MathFocus 9) Simplify: to combine or gather like terms creating and equivalent polynomial with fewer terms. Eg. 2x - 3x + 9 can be simplified to -x +9. (taken from MathFocus 9)

=**Lesson 6.2 Exploring Models for polynomials**= = **BIG IDEA:** Explore models of polynomials. =

=Homework Questions for Thursday March 15: Create five polynomials using this web site and write them down to hand in on friday.=

Please watch these videos by friday. I want you to watch these two different videos on using algebra tiles. They are super important to know for the rest of the unit. media type="youtube" key="C9-XZ9DHTK4" height="315" width="560" media type="youtube" key="CZpRH5si06g" height="315" width="420"
 * Don't worry too much about the 1x5 piece in this second video! All the other pieces are important.

=Lesson 6.1 Modelling with Polynomials=

BIG IDEA: Model and interpret situations involving polynomials.

**Definitions from the text book.**

 * Algebraic Expression -** the result of applying arithmetic operations to numbers and variables. (from MathFocus 9)
 * Polynomial -** an algebraic expression that is the sum of numbers and terms involving variables with exponents that are whole numbers. (from MathFocus 9)
 * Term -** a part of a polynomial separated from the other terms by addition signs. (from MathFocus 9)
 * Constant -** a quantity assumed to be unchanged throughout a given discussion. (dictionary.com)
 * Degree of a Term -** the power to which the variable in a term is raised; if a term contains two variables (eg. xy), it's degree is the sum of the exponents of the variables. Degree of a constant is 0. (from MathFocus 9)
 * Degree of a Polynomial -** the greatest of the degrees of the polynomial's terms.

Lets get started with polynomials. Here is a short video from the Khan academy about polynomials. The video explains the idea of terms and coefficient, but does not cover degree of polynomial very wel. media type="youtube" key="REiDXCN0lGU?version=3" height="360" width="640"

And here is a video of figuring out a polynomial where the variable x has been given a certain value! Exciting. media type="youtube" key="03yq7XsErqo?version=3" height="360" width="640"

The Khan Academy has many many videos if you are having trouble with an idea in math. But I will start by posting links and ideas right here. Following class on Monday/Tuesday I will take the definition of various ideas in class gather them from students and place them up here as well.
