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

3. Fractions to Decimals

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.

I unknowingly created my first YouTube videos a year ago when my dad gave me a digital camera. For my sister’s birthday, I made some how-to videos on “hooping”, a dance form using a hula hoop. She emailed me asking if it would be okay if she posted the videos to YouTube, and then added, “Well, let me know if it’s a problem because I’ve already posted them.” Jessie received so much positive feedback and requests for additional instructional videos that she created a how-to hoop dance YouTube group and a Squidoo Hooping lens featuring the videos. (Click on the link to see my first YouTube video. If you want to learn how to make a dance hoop, click on her “Other lenses by me” button at the top right.)

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!

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.

Say it. Write it. Simplify it.

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.

Fraction Test Retake Help

I hope everyone is enjoying the last few days of vacation. I promised I’d post some resources for people who needed to take the retake. Remember in order to do the retake, you must correct the original test. The answer keys are posted in the classroom window. Retakes will be Thursday at lunch, Thursday after school and Friday at lunch. The maximum grade on a retake is 85%. Test corrections for people not retaking the test will be due by Friday for a 2% increase. Remember all people must choose two problems and write a few sentences about how to do the problem correctly.

All Classes
The following resources are on my fractions website, but here are direct links to some of the areas you may want to focus on:
1. Adding & Subtracting Fractions
2. Change Percents to Decimals
3. Change Fractions to Percents
4. Comparing Fractions & Decimals
5. Comparing Fractions, Decimals & Percents
6. Saloon Slap Game: Compare fractions, decimals and percents

There is currently a scarcity of good fractions tutorials on the web. I was planning on making a bunch of YouTube videos over the break, but I’ve been without a whiteboard for a couple of weeks and just got one made yesterday. Ugh! I’ve been playing with iMovie but I can’t upload them because I haven’t learned how to configure my new computer to my Internet at home…. so what all that means is that the YouTube videos will be a little late in their debut. Sorry. :( The good news is that I will be available at lunch all week if you have questions. :)

Here are two videos in the rough because my PC wouldn’t recognize my iMovie.
YouTube Video: Find the LCM & GCF Using Venn Diagrams
Helpful for large denominators
YouTube Video: Writing Exponents in Expanded Form
This is a basic skill needed in order to divide monomials.

Remember there is a basic multiplying & dividing monomials video on a previous post. If the concept is gotten fuzzy in your mind over the break, it would be 5 minutes well spent to watch it.

Math 7*
I have one YouTube video up about negative exponents. It’s a fairly advanced one.If you are struggling with the basic concept, come see me or get help from a friend.

See you all soon and if you haven’t checked out the 2007 New Year’s Resolution post, I recommend it.

Fractions & Percent-Decimals-Fractions Test

The fractions, percents-decimals-fractions & multiplying & dividing monomials test is day 4 of this week. Math Tutor: Fractions is a great resource to help you prepare. This website that I created has tutorials, videos and fun games to teach you about fractions and how to change from fractions, decimals to percents. I’d love to hear your comments about the site. Leave a post.

If you haven’t see the YouTube video on multiplying and dividing monomials, I recommend it highly. It will help you to avoid common mistakes.

Multiplying & Dividing Monomials

A monomial is a single term. For example, 3x, -5xy and 7 are all monomials. When multiplying and dividing monomials, it’s a helpful to write the problem in expanded form. a^2*a^3 = a*a*a*a*a = a^5. (That looks weird. I’ll be happy when blogging supports math software!)

For a quick reteach of multiplying and dividing monomials, check out this video. It also discusses common pitfalls to avoid. [YouTube=http://www.youtube.com/watch?v=Z6T1BtXKZbs]
