Polar Coordinates and Equations--More than Pretty Pictures!

Great use for cardioid graphs!

Since our study of polar graphs and coordinates was abbreviated (and we had Thanksgiving in between) I wanted to provide a few resources for you to help with your test review, so here you go:

Written resources:

• Great examples from a professor at Lamar College
• Another math teacher's resources for students
• From the appropriately named "Math is Fun" website - examples of converting between coordinates
• How to create a polar graph using a table
• Using your calculator to create polar graphs
• An explanation and examples of all of the different polar graphs
• Free graph paper to download

Video/Interactive Resources (most require Java):

• Video tutorial of basics of polar coordinates and graphs
• Great interactive site to explain polar
• Interactive sites to create polar graphs (like our "web assignment") - found here and here 
• And don't forget my new favorite website for a graphing calculator: Desmos!

If you find another resource that might help a classmate, please list it in the comments below.

Test Time!

OK, it's time for our next test, so what changes do you need to make to be ready for test #2?  What do you do to prepare for a math test?  Can you think of anything that I might do to make the questions more interesting?  

Here is a cool graphing applet to show transformations of sine and cosine graphs.  (You will have to allow Java for this applet to run, and click on the links on the left side of the screen.)

I have a growth mindset about making videos to help you, so here's attempt #2.  (I also got a bit of advice from my friend Mr. Gonzales who suggested a "Crash Course" type video.)


And here's a lower production video for a quick review of even and odd functions.  (It worked at home, but now it says "converting," so I hope you'll be able to view this video!!  Sigh.)

Are these review videos helpful at all?  Please let me know!  

What improvements or other suggestions do you have?  

I'm still learning!

Graphs of Sine and Cosine

For my first absence of the year (several of your teachers will be attending this training) I tried to create a video version of our notes.

I must admit, the video is pretty terrible, but the instruction is adequate. :)  You can hear my pen tap on the screen, I used a couple words wrong (function rather than transformation; stretch rather than shift) I am sometimes too quiet and sometimes too loud, and I think at one point, you hear my cat purring in the back ground! BUT, I have a growth mindset about preparing these types of lessons for you, so I won't give up after my first fail.  And I didn't want to learn how to edit because this has already taken me 3 hours to create!

So please enjoy my version of sine and cosine graphs.  The notes for this section are here, but I'll have copies for you in class.

If you don't completely understand everything, have patience (and a growth mindset).  A classmate may help you and/or I know you can find countless other resources online to help with the topic.  I'll return on Wednesday, and we'll continue the discussion about trig graphs, but we'll have even more transformation fun in store.

Once you finish the video, please complete the quick survey about 

your learning and understanding.

If you have any additional suggestions, concerns, or questions, please feel free to leave them in the comments!  Thanks, and have a wonderful day.

2013-14 Begins NOW!

Welcome to our class!  

I know we're going to have a great year together.

I started this class blog a couple years ago, and I plan to utilize it with our class again this year for both math and non-math posts.  Please look over the blog rules page before commenting.

For your first post, please briefly introduce yourself.  You may share something from your Mathography, or you may include something new.  You only need to write a sentence or two...just please write something that will help us know you a bit better.

To help you get to know me, one of my favorite sayings is "Whatever worth doing is worth doing well." (What does that say about me as a teacher and a person?   How could that possibly be a hint about our class?  Hmmm...)  Another bit about me: last year, we wrote 6-word memoirs and mine was "I love to help find solutions."  Do you get how that is math-y, teacher-y, and applies to my IS job?  I also love technology, so we will experiment with sites and tools I find.  I have been known to waste a lot of time looking for the perfect, fun font.

This summer, I spent a lot of time with my family--here, at a friend's lake house, and in Hot Springs, Arkansas. I also spent time with friends, where we tried new restaurants, talked school stuff, and went to movies. I also visited two Presidential Libraries, and I highly recommend visiting any of them around the country!  I learned how to grill vegetables, and I enjoy cooking and baking.  (I bet you will love the ginger snaps I bring you!)  I was kind of "craft-y" this summer, and I made about 100 magnets for different people.

I also took at least one picture every day this summer, and I plan to continue taking pictures every day during the school year!

Some teachers don't have much time off, and I did a LOT of school work this summer, but it was mostly for fun and just good learning.  I took a free online course through Stanford called "How to Learn Math," and I know you will benefit from what I learned there.  I love to read pretty much anything, but this summer, I spent most of my time with educational stuff.  I enjoy some YA fiction (Allegiant is released on 10/22!) and I am also looking forward to the movie Catching Fire (11/22!)

My examples were too long, and don't feel obligated to write that much, but I'll be happy with all of your posts.

I look forward to getting to know you, and I'm so excited about the new year!  
Get used to hearing about #growthmindset!

Thank you for your comments!  
(By the way, I moderate the comments, so they do not appear until I post them.  Sorry for any confusion!)

Technology Survey

If you have trouble accessing this survey, please try the link here.

While you're here, why don't you follow me on Twitter and like our class Facebook page? ;)

Hooray for the End!

I can't believe it's already time to end the year!  It seems like you were just here last week completing your math-ography and survey.

Here's one last post for you, and I would really appreciate your feedback.  I think it is very important to reflect and learn from each experience, so I would like to know what you think about our class and my teaching.  In addition, for my "other" job, I think your feedback about teaching in general could help teachers new to LHHS.  The last part of the questionnaire asks you to reflect a bit on your own year.

I have created this survey that you may complete at any time this week.  Your feedback will help me improve my teaching, but please be considerate about how you respond.  (I accept your constructive criticism, but please justify your responses--just like on our tests!)  You do not have to include your name, and you do not need to complete every question.

If you want to share your summer plans, feel free to post in the comments.  (My sister will be here in 2 weeks, so for me, summer starts with family fun!)

A few end of year quotes for you...

“Believe in your dreams and they may come true; believe in yourself and they will come true.”

“Nurture your mind with great thoughts; to believe in the heroic makes heroes.”

“Even a mistake may turn out to be the one thing necessary to a worthwhile achievement.”

Thanks so much for your time!

More importantly, thanks for a great year!

Math Memoirs

Not that anyone is counting or anything, but hooray for the last weeks of school!   For an extra credit opportunity I'm "borrowing" this idea I found on another math teacher's blog.  (You can look at her post to see her students' samples.)  She actually took the idea from this story on NPR and from http://www.smithmag.net/, a website where Six Word Memoirs can be shared.

Using only 6 words, create a memoir of your year in our PAP Pre-Calculus Class.  Your sentence/phrase should make sense, but it does not necessarily need to be a complete sentence.  (I'll accept sentence fragments!  Don't tell your English teacher!)

Details...

• Complete your memoir on a page at least 8.5" x 11".
• Include your sentence, and then somehow illustrate your memoir.
• You may type or hand-draw your "project."
• Please be neat, colorful, and creative.
• Your project should fill the page.
• Have fun!

Your math memoir will be due on Monday, May 20, and it will be worth test points.

If you would like (need) additional points, either on your HW average or to boost your HW/Quiz category, you may create an additional Six Word Memoir about your "non-math" life.  

Feel free to post your sentence here, but please turn in your projects by next Monday.

Thanks, and I look forward to reading all of your memoirs!

By the way, here is my memoir, created while I was proctoring an AP test. :)   I think this sentence captures my math and IS jobs.  I'm still working on my illustrations, and I'm still working on my personal memoir.

I love to help find solutions.

Here are a few finished products from last year!  I think these memoirs are awesome!
