Multiplying and Dividing Fractions

While I am thinking about, I want to make sure that everyone is familiar and comfortable multiplying and dividing fractions because it will come in handy here soon. I found a couple of videos I want to share. The short one is this video that talks about some of rules of muliplying and dividing fractions and it's only 2 minutes long. I also found another video that is from Khan academy, and he has done some other videos I have seen. Here are also some follow up problems from Khan for multiplying and dividing fractions that you can do on your own. The Khan links also cover reducing before multiplying which can help you make calculations quicker mentally. Check it out!!!!!!

Substitution video

Ok, So I know some of you like to watch videos, but hate watching boring math instruction videos. We are going to cover solving systems this week and I found this video that hopefully will introduce you to solving systems by substituion. There is also another video about solving systems by graphing. I feel this is one of the better math teachers with videos up on the web so I would appreciate if everyone can at least take a look at both of them before next week. They are both about 8 minutes long so they won't eat up a lot of your computer time. If you want to go visit the website, it is yaymath.org. Unfortunately I am still looking for something about solving systems by elimination. Let me know if you have questions. See you Monday.

Test tip

If you get stuck during the test tomorrow, draw a picture. Sometimes it helps.
