Multiplication, division, laser TVs, logs.

Well today I hopefully have something for everybody.

  1. The site DoubleDivision.org shows you an alternative long division algorithm, which takes the guessing away from estimating how many times the divisor goes into what needs divided. Also called 1-2-4-8 division.

    This is a pretty cool way of dividing! The interactive tool shows you the steps right there for any problem you might come up with.


  2. At MathLogarithms.com you can download an ebook by Dan Umbarger explaining logarithm how's, why's, and wherefore's in all detail for students.

    Great resource for precalculus students.


  3. You might also enjoy an alternative way to multiply called lattice multiplication. I did! It seems pretty simple.



  4. And lastly, if the math topics didn't interest you, how about my hubby's newest website called Laser-TVs.net ... It's about a totally new way of making TVs using lasers.

One Mathematical Cat, Please! said…
Hi... I'm new to "Google Blogger," having just created one to help my users give me feedback. So, I hope I'm using the correct protocol here!

In playing around, I typed in "math" and came across your site. Lots of your entries seem to be people needing worksheets for homeschooling... so...
you might want to take a look at my site.

I'm putting an entire high school mathematics curriculum online, using MathML (MATH Markup Language) and Javascript to create randomly-generated, correctly-displayed math problems. Students can practice to their heart's content... different problems every time. They can print out randomly-generated worksheets + solutions (a different worksheet every time you click) for practice away from the computer (or for quizzes and so on). It's all totally FREE. (I'm a MathML Evangelist... one of the purposes of the site is to spread the word about MathML.)

I have thousands of users around the world. Because MathML isn't well supported yet, the downside is that you need a PC (not a MAC), Internet Explorer 6 (or above) with MathPlayer installed (free and easy, links on site).

Hopefully this can be of use to some of your home-schooling members. And (even more hopefully) some of them will get interested in using MathML + Javascript to create similar web exercises of their own!

Please feel free to have anyone contact me with questions about my site... I always like to know who is using it... and how, if it's working well for them... and so on.

Have a great day!

Conversion chart for measuring units

I was just sent a link to this site; all it is, is a handy one-page printable conversion chart for various US measures, metric measures, and US vs. metric measures. Includes even a comparative Fahrenheit vs. Celsius thermometer. http://metricconversioncharts.org/

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 i...

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...
