## Converting Fractions to Decimals to Percents

The eighth graders are reviewing converting fractions to decimals to percents. They need to create notes to remind them of the process and they need to be prepared to explain how to do this to the 7th graders. Next week the 8th graders will have to teach the 7th graders, then there will be a pair quiz on Tuesday consisting of an 8th grader partnered with a 7th grader. So be prepared!

Here are some YouTube videos to support you:

1. My (MVMS) famous “Decimals to Fractions” YouTube video

2. NASAConnect Percents, Fractions and Decimals video – a fairly basic video; if you really struggle with this concept, you may want to start with this video

Here is a website that I created about fractions. Go to the module that says “Fun Fractions Games and Practice.” The following games will help you practice:

a. Equivalent Fractions Game

b. Quia – Equivalent Fractions Concentration

c. BCC Saloon Snap Fractions, Decimals and Percents Card Game.

Enjoy… and good luck on Tuesday’s quiz.

## TeacherTube, an Educational Alternative to YouTube

Finally someone got it together and created an educational YouTube-like site. It’s called TeacherTube.com and it was launched this month. It has 11 channels covering different subject area and has tutorials and student projects on it. Maybe you have something you’d like to share with other students to help them learn.

Here is a video that I thought was interesting called “Technology Fear Factor.”

## Learn About Biodiversity: Bio DaVersity Code

Man is not alone on this planet. He is part of a community, upon which he depends absolutely. Ishmael, Daniel Quinn

Check out the latest clip from the folks at Free Range Graphics. This video is called Bio DaVersity Code and teaches about the importance of biodiversity and that humans are part of the web of life. You may recognize the plot.

Much of the ecological devastation has been caused because people don’t believe we are part of the web of life, and hence they don’t respect the Laws of Nature. I’ve been amazed over the years when I taught science that a number of my students didn’t even know that humans were animals!

If you want to read an excellent book that will transform the way you look at humans in relationship to the other creatures on this planet, and one that provides a possible vision for people as stewards of the planets, I recommend the book Ishmael by Daniel Quinn. It will change your life. It did mine.

## My First YouTube Video: How-to Hoop Dance

YouTube is a free website with a tagline of “Broadcast Yourself.” It’s full of junk and gems and it has great potential to support learning.

All of the positive feedback from the dancing videos inspired me to make some math videos. I’ve received dozens of appreciative emails about the videos. Now I have two YouTube groups specifically for helping you to learn math. One group is a pre-algebra group and the other is about Vedic math, the ancient mental calculating system from India. Enjoy!

## Hubble Space Telescope: The Most Important Image Ever Taken

This  beautiful video talks about the most important image ever taken by humanity.

For more amazing photos from the Hubble Space Telescope, including beautiful screen savers, go to HubbleSite.org. Looking at these magnificent pictures can open you heart and remind you that you are a part of this glorious Universe.

## Fractions to Decimals Song

Here’s a Math 7 classic song, “Fractions to Decimals.” Feel free to sing along at home.

The key to changing fractions to decimals is that you need to understand what the decimals mean. For example, 0.9 is 9 tenths, 0.07 is 7 hundredths and  0.103 is one hundred three thousandths. If you’re not solid with this skill, come in and get help.

## Exponents: Zero, Evaluating & Negative Exponents

Here is a video explaining why any number to the zero power is equal to one.

Careful: -2^0 = -1.

You may also be interested in watching this video by Nutshell Math on exponents and using substitution and evaluating expressions that have exponents.

Here is another explanation of negative exponents. We’ll be covering more on negative exponents next week. It’s a good idea to watch the video to get a preview.
