A few weeks back I read this news article about poverty in the United States. It mentioned that nowadays, 79% of the US adults (of all races) experience periods (of at least one year) of joblessness, life on welfare or near-poverty. Among US whites, this figure is 76% - almost the same.

I also know about this because many have written to me how they'd like to purchase my materials, but cannot afford them.

It made me sad... but please realize I'm not mentioning this article to differentiate the people of the USA. I don't feel that way at all! I know poverty exists everywhere and among all races, and at different intensities. My husband and I have lived "hand to mouth" in the past, so I know how that feels. We all are in a "same boat" in a sense... we go through similar things.

But, reading that, I started thinking of an idea of how I could help in a small way.

So, you can get one my books at Currclick for PAY WHAT YOU WANT (Math Mammoth Percent). This means even $0.00. So, you can download it even for free, whether you are poor or rich, whether male or female, tall or short... and whether you live in the US, Europe, Africa, Asia, South America, Central America, Australia, or anywhere else. I hope it helps all of you in your math teaching/learning!

Geometric art project: seven-circle flower design

Image
I got inspired by the blogpost Art School | Geometric Design with Islamic Art where Deborah shows how to make a neat flower design with seven circles , using a compass, and then coloring it using 2, 3, or 4 colors (or however many of your own). I think it ties in neatly with mathematics, and lets students practice drawing circles with a compass.  My girls loved the art/math project. Here are pictures they made: Here are step-by-step instructions for the flower design: 1.  Draw a line and a circle so that the circle's center point is on the line. Then mark the points where this circle intersects the line. 2. Use those points as center points, and draw two more circles. The radius is the same all the time, so make sure you don't change it on your compass!We used 5 cm as the radius, and that made the whole design fit neatly on a regular letter size paper. 3. Now note the two points marked in the picture. They will be used as center points in the next

Meaning of factors in multiplication: four groups of 2, or 4 taken two times?

Someone asked me about the interpretation or meaning of the two numbers in multiplication, such as 4 × 2. Do you view it as four groups of 2 , or as four, taken two times ? Here's their question: "...I noticed that your explanation about how to interpret a math phrase, such as 4 × 2, is different from how I have understood it and taught it to my older daughter who was using RightStart Math at this level. Let me explain:  I see that you are using the first factor to denote number of groups and the second factor tells how many are in each group (4 × 2 would be interpreted 4 groups of 2).  On the other hand, I have taught and thought of it reversed, with the first factor telling how many are in each group and the second factor telling you how many groups (4 × 2 would be 4 taken 2 times).  I know that the difference in explanations does not ultimately change the product, but I am wondering what you thoughts are.  When I conceptually picture what I'm doing I see it as 4
