- Apple released their latest quarterly results this week and they were rather impressive. Here are just some of the numbers:
It sold 37.04 million iPhones – its flagship product – and 15.43 million iPad tablets, doubling from a year earlier and easily outpacing already heightened expectations for a strong holiday season. That helped swell its warchest of cash and securities to almost $100 billion – more than enough to plug December’s U.S. budget deficit and level with California’s 2012/13 spending plan.

Please write each of those big numbers in scientific notation.

- Play around with the Cold War Kids video and try to answer the two questions from the lesson:

a) If we set all of the tracks before we start, how many different videos could we watch?

b) How many clips did each musician have to record?

c) Bonus question: If we started watching all the possible different versions we could watch starting Tuesday in class, and only watched during our Algebra class (and did nothing else - you wish), on what day and at what time would we finish watching the videos? (Helpful link: AHS Calendar) - Here are two interesting articles about probability that you might be interested in.

5 Worries Parents Should Drop, and 5 They Shouldn't looks at what parents typically fear will happen to their kids (but is actually pretty unlikely), and what they should be concerned about (because they have a higher probability of happening).

Chances Are looks at a conditional probability problem involving the likelihood of having breast cancer is you have a positive mammogram. We won't be getting into conditional probability this year, but it's still an interesting and important article for you to see how probability is something you need a good handle on in order to make good health care decisions.

- On your personal blog, create a new post titled: "Scientific Notation"
In the post explain to your reader how to solve this problem:

Multiply, then write your answer in scientific notation: (4.5 x 10^{11})(3.1 x 10^{4})

Make sure you thoroughly explain the steps and what you are doing*so that someone that doesn't know how to do scientific notation can understand it*. (Hint: Just in case, the correct answer is 1.395 x 10^{16}).

Remember, three ways you can "type" exponents on the blog:

1) Use the ^ key (shift-6). So 5^2 is 5 to the second power. This is the easiest way and probably the way most of you will do it.

2) Create an image using the tools I showed you first semester, then upload that image.

3) If you're into HTML, the code for superscript is <sup>, so you have to switch to HTML mode (there's a button at the top of your blog post window that says Compose, right next to it is HTML) and insert the code on the HTML screen. The code would look like this: 5 <sup>2</sup>

When you switch back to the compose window, you'll see a nicely done exponent.

Then visit the moodle and paste in the URL of your blog post. - Prepare for the Scientific Notation Assessment on Friday . Please study.

- Watch and complete the Exponent Properties Involving Products video.

Recall that there are three main parts to the video: an examples and explanation part, a Guided Practice part, and a Self-Check part.: Just what it sounds like. I explain how to do the problems and work through some examples. You don't need to write anything down (unless you want to), just watch, listen and learn. Pause the video and replay parts if you need to.

Examples and Explanation: I give you a problem, then ask you a series of questions with about 5 second pauses between questions for you to think about it and answer it for yourself. If you need to, pause the video to give yourself more time. Again, you don't have to write anything down here (although you can and it's often a good idea to)

Guided Practice**Self-Check**: I give you a problem, ask you to pause the video, write the problem down in your notebook and solve it, then play the video again to check your work. You may need to pause the video again to view the solution if you need more time. These problems you definitely need to write down in your notebook and then - this part is new - go to the Moodle and enter your answers for the self-check problems on the Moodle. - If you haven't turned them in yet, remember that your final exam corrections are due by Friday (Haley and Pedro, you do not have to do these.)

Happy New Year everyone.

The basic structure of our class will be the same. My views on homework haven't changed - I really don't think homework should be a big part of your grade (it's a time to practice and get better, not get graded) - and I also don't want to take class time just to check to make sure you've done it (I think there are better uses of our class time).

Based on the feedback that many of you gave me on the evaluation, however, you have a different opinion, so I'm going to compromise a bit. I'm going to bump up the "Preparation" category to 15% of your grade (from 10%), and drop the Skills Assessment to 67.5% and the Final Exam to 17.5%. Each day we have class you will have some kind of homework assignment that you'll need to submit on the Moodle that will be graded for completion.

Once you feel like you completely understand these changes for second semester, please fill out this form to indicate your understanding.

- For
the homework videos, you'll still need to watch them and complete the
self-check problems in your notebook, but now I'm going to ask you to
submit the answers to the self-check problems on the Moodle. (That way I
don't have to take class time to check that you've done them.)
- The online pre-assessments will still be on the Moodle, but now I will grade them (again, for completion).
- On nights when you don't have a video or a pre-assessment, you'll have some other short assignment - perhaps a couple of homework problems or a blog post - and you'll submit that on the Moodle as well (if it's a blog post, you'll submit the URL on the Moodle).
