This blog will serve as the website for Mr. Carlton's classes. Here you can find information on what's happening in class, assignments, class rules and procedures, and other things that I might want to share with you. To the right you should see a heading Site Navigation. Under that heading are links to different sections of the website. You can read about me in the section below that. If you want to find something from a certain day, the Blog Archive provides a useful listing of posts by date. If you want to find a post, but only know what it is about, you can click on the label that it might be under. I have also included links to some websites I appreciate, first to other math-related stuff, and then to cool websites that I like.

If at any time you get lost, coming to this entry named "home" will give you options to go to different parts of the site that might be important to you.

Assignments

The doctor says...

Alright, I was gone again today. It's pretty frustrating. I went to see the doctor today and he said I have a virus, so hopefully I'll be better in a few days. I'll probably miss tomorrow, too. Having said that, I did come in to make sure there was learning going on. I want you guys to be ready for the CST next week. Hopefully the sub gave you the packets and you were able to show each other how to work on problems. The same thing will happen tomorrow, whether I'm able to make it to school or not. As promised, here is a link to the released questions from the CST. The link is a download, so that should start when you click it.

Lesson 9.4 (Day two)

No new notes today, but here is the worksheet that we started in class.

I stayed after school for anyone who needed to make up or re do the quiz from last Friday, but no one showed up. That means you need to make sure you schedule a time with me soon.

Lesson 9.4 notes (three theorems)

Theorems

9.4.1 If a tangent and a secant (or chord) intersect on a circle at the point of tangency, then the measure of the angle formed is half the measure of its intercepted arc.

9.4.2 The measure of an angle formed by two secants or chords that intersect in the interior of a circle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

9.4.3 The measure of an angle formed by two secants that intersect in the exterior of a circle is half the difference of the intercepted arc.

Here is tonight's homework: pages 592-593, questions 1-8. (The first four questions are really just asking what the theorems say, so look at the wording in your book carefully.)

Sadly sick again

Well, this was another one of those mornings when I was too sick to get to class. Worse, I didn't have anything for you guys, so hopefully the day was alright. Because of that, we couldn't make up or re-do the quiz after school. That means we'll need to do it other times. If we can do it tomorrow during the staff meeting, we'll do it then. If not, Thursday after school will be the best time.

Don't forget to bring your text books to class on Wednesday.

Quiz re-do tomorrow, and a worksheet

Don't forget that if you need to make up the quiz from Friday, I'll be in my room after school from 3:00-4:00 tomorrow (Tuesday, April 22). The sorts of stuff you'll need to be able to do is on the post below this.

The assignment today (which was also intended to help you get ready for the quiz re-do) is here. Download and print it if you need to.
