Another change in plans

Hello everyone. You may notice that those last 2 posts do not have questions. It was my goal with this semester as with last semester to keep on top of posting our class events and getting feedback from you. I have enjoyed reading all 1400 comments so far this year. At this pace, we would hit over 3000 comments, with just 3 classes! Last year there was 3300 comments with 5 classes. This is truly amazing. I think this blog had a lot to do with how well we did as a class on the fall final. Not only that, but due to the increased traffic to the website, I’m now hit #1 on Google!

However, I am juggling too many things right now. At school I’m trying to update blogs, add moodle activities, grading papers, grading benchmarks, making lesson plans, and all the other stuff associated with being a teacher. At home I am trying to keep up with my 2 sons’ activities, write my Master’s Thesis on Educational Technology (50+ pages of writing and research), as well as prepare our home for a new baby due to arrive in June. I can’t keep up with it all.

So I have decided to use the blog only for listing HW and the day’s activities. But don’t worry, we will still have our posting for points! I will be using the forums on Moodle to create discussion on our current topics of study. This has benefits that the blog does not. For one, you can see your “grade” for the comment. This will then give you an opportunity to fix/add to it. It is also more of a discussion, so dialog can go back and forth if needed. It will be easier for me to track so I won’t have 110 emails I have to read and record. Plus with the practice benchmarks on Moodle, a calendar for upcoming dates, and all the other features, it just makes sense.

So thank you all for the comments. Happy Moodling!

Similar Solids

So what happens to a solid’s perimeter, area, and volume if you double the edge length? That’s what we looked at today. We started class going over HW #4 review on the board. We then did a quick investigation followed by some examples of BM 26. Here are the notes and the HW is #5 Similar Solids WS.

BM 25-27 Review

First off, we check #3 from over the weekend and went over it. The we took our first HW Quiz (#1). After that, we just continued to review for BM 25-27 on similar triangles.

Homework: BM 25-28 Review (BM 28 is optional right now). Also, bring a calculator if you have one.

8.4-8.5 Similar Triangles

Now the benchmark problems!

Today we looked at similar triangles. The main way to prove triangles are similar, some additional ways to prove they are similar, and some examples of the upcoming benchmarks (BM 25, 27, and 28). Notice there are a lot of “proving” triangles are similar? Don’t let that get you down, it’s our only “proof” benchmark.

The assignment for today is #3 483 #9-27 (odd), 39-47 (odd), 50-53, 55, 62-65. We will continue with these sections next week.

Coming Up: HW Quiz on Monday, 1/14

What are the various ways to prove triangles are similar?
