to do Homework! Hopefully, everyone is enjoying and being safe with these couple of days off of school.
What a great time to be sure all of you homework problems are complete as we finish up chapter 2.

Do you understand graphically...what tools are you using?
We will be wrapping up the Functions Graphing Chapter this week (Chapter 2)
There will be about three new objectives we have to learn by mid-week and the Chapter 2 Test will most likely be Thursday or Friday and cover all the chapter 2 material except 2.7/2.8 (which will not be covered or assessed).
Here is an overview of the new learning targets for this week:
In addition, we will be practicing material (especially real-life applications) of the functions material we learned in section 2.1-2.6.
Speaking of real-life applications. Most real-life situations that can be modeled by functions are not "factorable". If you are completing a take home quiz or have a quiz coming up you need to be very familiar with finding zeros of functions and using other graphing calculator tools like intersections, etc.
For the large number of you who have not purchased your own graphing calculator, you are putting yourself at a disadvantage. I did not have mine at home this weekend and did find some online versions. If you are using any online application be sure you can find zeros and intersections of functions. A quick search (and updating my java) did allow me do find one decent online calculator. You can try this one if you have not found something already. http://www.calculator-grapher.com/
Again, we are not just drawing graphing graphs. We are finding solutions. Many online version or "apps" draw nice graphs. But you need to do calculatoins with precision and are expected to be able to do that at home.
If anyone wants to share a good site and/or post some images from online calculator website. Please do so in the comments section.

Here is an overview of the new learning targets for this week:
Be able to …
factor using multiple techniques (including completing the square and by grouping)
write a quadratic equation given a graph and vertex
(connect to transformations understanding)
find all zeros (real and non-real) of polynomial functions and understand multiplicity(connect to transformations understanding)
In addition, we will be practicing material (especially real-life applications) of the functions material we learned in section 2.1-2.6.

Quadratics!
This week will be another week partially interupted by the NECAP exam. The good news is that the next few sections we are covering are really review of Quadratics and Polynomials (and may help you prepare for the NECAP as well).
Tomorrow, we will review different types of factoring and discuss a good common approach to factoring Quadratics and Polynomials and will practice with a fun puzzle activity.
I really need to get a good idea of how well you know the 2.3 - 2.5 material and if you completed this weekends handout, that will give me (and you) and great idea of where you are at.
In fact, as a bonus, if you are reading this tonight and go to my website: http://www.mpsri.net/page.cfm?p=1567 you will find worked out solutions to 2.4 - 2.5 posted under Chapter 2 resources.
If you bring in any evidence that you review this site before class tomorrow, or just simply comment that you checked out this blog tonight, you will earn 5 points extra credit for this Homework. I will try and post another handout on the website tonight too, that give you a better description of how to score yourself.
Good luck on the NECAP and don't forget, you can access many of the released problems from 2007 - 2011 and check your solutions if you do a little poking around on the internet.

Function Graphing (Ch. 2 week 1)
General - This week we will be our understanding of graphing different types of functions compared to their parent functions, describing those comparisons algebraically and using math vocabulary, and recognizing even and odd functions. We will be using a graphing calculator lesson to understand those connections and you will get some feedback (in fact some sample student work with feedback will be posted on the website after Tuesday’s lesson. The two main text sections this week are 2.2 and 2.1.
3 Key Graphing Process Goals
- Numerically – Recognize and label key feature coordinates (usually 3-5) and show work using a table of values
- Algebraically – Understanding from various forms of given function(s). y = a (x – h)?+k and where it will graph relative to parent function (translate, reflect, dilate, etc.) because of the given coefficients.
- Verbally – Once you see the patterns, you need to build your math vocabulary to describe what is going on with each function
3 Key Products (All due the class after they are assigned)
· Text HW 2.2 70/12-30 show given graphs with key features labeled, draw resulting diagrams using a different color pen. See sample solutions to HW 2.2 on website for guidance about what level of detail is expected to earn a 4 for homework
- Handout 2.2b – Backside of Transformations Handout (after receiving exit slip feedback)
· HW 2.1 61/Practice 1-27,34
Most likely will have a 2.1 – 2.2 quiz after Weds.
Other Comments
If you did poorly on the Ch. 1 Test, you are expected to make corrections to your exam , redo any missed or incomplete Ch. 1 homework and then see Mr. Steppen about a retake exam.

2009 Necap Practice Exam and starting 2.1
Happy Monday Night,
As I mentioned in class today, I am going to start posting a Sunday night post so everyone in my Trigonometry class is expected to check in at least once a week, usually Sunday night after 8 pm is the best time. In fact, if you are reading this right now you should become a follower of the blog and check out to see if there are settings to automatically update you when a new post has been submitted.
Mainly the blog will be a short summary of what we did the previous week and a preview of what is coming up for the week ahead. I will informally monitoring to see who is participating. Many of your upcoming college courses may have an online element, so participating with this is good practice in a different style of communication.
This post is a bonus because I just got a list of who is missing class this week due to the NECAP writing test. The majority of you are not missing Trig. class (lucky you). So the plan is to continue on to Chapter 2 (Section 2.1 - 2.2 Graphing Functions this week.
For my D-period students, you have already been given the task of completing the 2009 Math NECAP released items for homework by Wednesdays class as Homework [20 points]. You can access my website to get that document (see previous blog post for a direct link to website). However, if you want a printed out copy I was able to print out 25 copies today and for the first five D-period students that stop by 225 in the a.m. I can give you a copy. In fact, you will earn extra credit for being the first to read this blog and follow up! For my C-period students, you will receive a copy in class tomorrow.
I will see everyone before the NECAP writing assessment, but in any case good luck! And, by completing the 2009 released Math Items you will be already preparing for the Math NECAP in two weeks. For my few non-11th graders, the questions are good practice and most relate to our class content anyways.
Life is just a circle.
