Ellie’s Math 7 Blog – Help with Fractions

Ellie is a 7th grader (actually she must be in 8th grade by now) in Canada. Her blog about 7th grade math is fabulous. This link takes you to games, PowerPoint presentations and other useful information about how to do fractions. Click on the “archives” link to find out about other math topics.

This is an amazing website! Doesn’t it make you want to create your own blog? If so, feel free to find math resources that other kids would enjoy and we’ll post them on or class blog. Just add a comment about a cool resource you found.

Vedic Math Site

Vedic math is the math of ancient India and it’s coming back in vogue. It’s an easy and fast calculating system, and one I wish we had more time to explore in class. The cool warm-up (that sounds funny “cool warm-up”) we did today was just one example of how different and interesting math can be using this approach. Check out some of my YouTube videos and other resources on my Vedic math lens. Also if you want to see the video similar to today’s warm-up, click on the “Easy Mental Mathematics” video.

There are lots of fabulous tutorials on the “Vedic Math Tutorial.” Also explore on the “Vedic Maths India Blog.” There are dozens of posts explaining how to do Vedic maths … and you may recognize a math video star! (By the way, “maths” is not a typo. Almost every English speaking country in the world says “maths,” except the United States.)

Financial Literacy

There are a number of resources available to help you learn how to be financial savvy. Talk to your parents or other people who know about saving and stocks. Let them know about the stock market project we’re doing and get free financial advice!

I wish that our school system focused on financial education and being a conscious consumer. Check out this article about American debt. It has some amazing statistics, such as 43% of American households spend more money than they earn. In plain math terms, earnings < spending = DEBT!

One super valuable piece of advice I have for you is that when you get a raise, keep your spending habits the same and invest the extra money from the raise. Most people get a raise and start to spend more and their lifestyle gets bigger than their income. Uh-oh.

To help you make intelligent financial choices, I created Money “Cents” for Kids, a lens for parents, kids and teachers. It has resources and games, and stuff for your parents too.

Remember the “Rule of Three” that we talked about the first day of school? I included that on this site. Imagine what a positive impact we could make if everyone taught several friends the Rule of Three. Make a commitment to tell three people this week about it.

When I was in 9th or 10th grade, my friend David introduced me to a book called “Flatland” by Edwin Abbott. It’s a short read about dimensions. A 3-D sphere visits the 2-dimensional world of Flatland and opens up new possibilities. Now someone has created a short video called Dr. Quantum Visits Flatland. I hope you like it. I sure do. The book is great too.
