Well, hello to the 3 of you still reading this blog…

I took a loooong break from blogging. 🙂 This past month I have been doing a lot of transitioning (between teams) at IHOP and I have been trying to keep my classes at The Daniel Academy together. Planning lessons and grading papers tends to take the creative blogging out of me. ;-/ 

However, after 1 more week of classes and then 30 finals to grade the next week, I will be done! I am glad. It has been a long and hard year, as most people at TDA can testify to. Not without it’s rewards, that is certain. And I will be very sad to say goodbye to my students. This thing I can definitely say… mathematics aside… I definitely have two of the best classes of students at the school. I enjoy my students so much. 🙂 I am not sure how many, but I know that some students will be moving onto other schools or other cities next year. I am really going to miss them.

And, I will be teaching at The Daniel Academy next year! Two classes, hopefully Pre-Calculus and Algebra 2. But if there is not a high enough enrollment for Pre-Calc, then it will be Algebra 2 and Algebra 1. So, all you students out there… sign up for Pre-Calculus! It’s going to be a blast. 🙂 I am very excited about starting things fresh next year. I have a lot of ideas brewing in my mind, and I am looking forward to setting some standards from the beginning with the students. And having class 3 times a week will be wonderful. More time for creative stuff and discovery type of lessons. Good stuff. 

Well, I will leave other updates to future posts, but they include the addition of a very furry individual to my life! His name is Miles. More info to come later. 🙂

Two things to report!

#1 Today was the first day of The Daniel Academy!

A few highlights:

– Having 20 min left of Algebra 1 and having already finished the stuff I had planned for the day… that took some quick thinking!

– Waking up a student three times

– Transitions are crazy… both the students and the teachers change classrooms.

– My math posters arrived today! Hurrah! I will probably put them up on Thursday…

#2 My sister is coming on Friday! I have high expectations for a very girly weekend. Involving make-up, nail painting, shopping, sight-seeing and of course the prayer room. I can’t wait till she comes!!!!!!

Functions

I thought it would be good to update my blog with a quick note. No time for preparing witty thoughts and diatribes. I am slowly yet surely creating lesson plans, so the thought on my mind now is…

(drum roll… ) How to teach functions! Functions are a basic concept of algebra. The concept of taking two groups of information and relating them. We do it in every day life. Such as the price of gas and the number of gallons your car needs. Or perhaps on the more spiritual point of things – how many chapters in the Bible you read a day. They are both simple functions. The fun begins when you take the information and create a formula and then graph it.

Ah, now to ponder the topic of Direct Variation and how best to teach it.

One down…

Seventy-one to go. Phew… I have been studying and perusing my math books for several hours today, and I am pleased to announce, that I have one lesson planned! Hurrah! 🙂

Oh dear, reality check…  one out of seventy-two complete and about three weeks before the whole shebang is due.  Back to the grindstone.

Logarithms!

 I am sure most of you readers will not be interested in my mathematical marvels, but I am thrilled to death. Well… I was studying the Sound Reference Handbook by Yamaha today (as a part of my quest to get more technical knowledge of sound) and I made an amazing discovery!  I was thrilled today to discover that our ears interpret sound logarithmically! Ah logarithms… I sigh with fond memory of many math classes 🙂 … Here is the graph of a logarithm…

Log base 10 of X

What does it mean? Well, I am pleased to tell you that our ears interpret equal distance between octaves of sound. (Low A versus high A) However, octaves are actually in a 2:1 ratio! Every time you jump an octave, the distance between the two notes doubles! Technically it is not distance but actually the speed of the waves of sound double! For example, the note ‘A’ is at 440 hz (or 440 wave cycles per second), jump an octave, 880, then 1720, then 3540 and so on. But although the distance doubles each time, our ears perceive it as the same! It is fascinating how God has created the human ear. I love it!
