### Don't Fear Failure

One of the problems I think we have in schools is that we train students to fear failure, to avoid it at all costs. Now, to be clear, I'm not suggesting you go out and fail all your classes. But I am suggesting that you should take some risks in your learning. That instead of avoiding things that are hard (because you might fail), you challenge yourself to step up and take on things that are difficult.

I think sometimes students would rather not try (and fail) than try and fail. In the first option it's easy to say, "Oh, I just didn't try." But in the second option it's much harder, because you have to admit that you did try and still weren't successful. But here's the key - almost anyone who has done anything worthwhile has failed. Not just once, but multiple times. We often learn more from trying something and not succeeding than we do from trying something and succeeding, especially if we limit ourselves to only trying "easy" things that we know we'll be successful at.

Here are a couple of videos that illustrate this point that I think are worth your time. The first is from the TED Conference I attended, which speaker Brene Brown (who also has an excellent TED Talk) described this way:
You know what the big secret about TED is? . . . This is like the failure conference. No, it is. You know why this place is amazing? Because very few people here are afraid to fail. And no one who gets on stage, so far that I've seen, has not failed. I've failed miserably, many times.
The key is still to try hard things, even knowing that you might fail, but then learning from it. So the first video is from TED Fellow Myshkin Ingawale. It's a little over 6 minutes, so please take the time to watch it. The important point to realize is that he built this device - and it failed. So then he built it 32 more times until it worked. After watching this video, think how important his invention is and how many times he had to "fail" to get a working version.

The second video is designed to be motivational, but I still think it has a good message about "failure."

So, what are you willing to try (and perhaps fail) at?

### Seriously. The Next Six Weeks Can Be Tough

The next six weeks can be pretty rough for students, both due to our schedule and due to the content in your various classes.

First, let's look at the schedule for Algebra for the next six weeks:
• This week we meet for 2.5 days (PLC day on Wednesday, furlough day on Friday).
• Next week we meet for 3 days (Presidents' Day on Monday).
• The next week after that we meet for 3 days (Parent-Teacher Conferences Thursday night, no school on Friday).
• The next week we only meet three days, and two of those are shortened classes (due to TCAP, we meet Monday and Tuesday afternoons for a shortened class and Friday regular time).
• Then the fifth week we finally have a full week (four days of Algebra.)
• The sixth week is a full week, but we have a shortened class on Friday for the Arapaho Assembly, and it's the week before Spring Break which means lots of stuff will be due in many of your classes.
With all of those disruptions to our schedule, it can be very hard to stay on track (and that's assuming you don't get sick/miss class for any reason).

Second, the content. In Algebra we'll be learning about polynomials, including factoring, which is a topic that is typically tricky for many students. We'll also be taking our midterm. In your other classes teachers will also likely be trying to finish up units before Spring Break.

When you put these together it often turns into a very rough six weeks for students, particularly for freshmen who haven't been through it before (in high school, anyway). You really, really, really need to focus and stay on top of things over the next six weeks. If you do, you'll be able to enjoy Spring Break and come back refreshed and ready to learn for the remainder of the school year. If you don't, you'll end up very stressed, your grades are likely to go down (as will your enjoyment of Spring Break), and most importantly your learning will suffer.

So make a plan for how you are going to stay focused and on top of things. Be sure to come in for help when you need it (not just my class, but all of your classes), or if you just need to talk. And help each other out; remember, Warriors always take care of one another (and themselves). This is an excellent time to put that into practice.

If you have about 6 minutes, I think you might find this video worth your while. I think he shares a great message about the impact you can have on others' lives - often without even realizing it.

So what do you think, do you want to try to be an everyday leader? Can you create a lollipop moment today?

3. 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.

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)

4. 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.

We began with our assessment over Zero and Negative Exponents (key, pdf).

We then practiced with scientific notation and explored the effects of exponential growth on a retirement program (lesson, pdf).

1. Check the portal for the results of your assessment, fill out your student checklist with your results, and make a plan for retake (if necessary), including making an appointment.

2. 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 1011)(3.1 x 104)

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 1016).

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.
3. Prepare for the Scientific Notation Assessment on Friday . Please study.

### Tuesday, January 3, 2012

We began with this opener (pdf).

We then talked about how first semester went and about adjustments for second semester. We then learned a bit about multiplying with exponents (lesson, pdf).

1. If you haven't yet, review the adjustments for second semester and complete this form indicating that you've read and understand them.
2. 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.

Examples and Explanation
: 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.

Guided Practice
: 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)

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.

3. 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.)
