Are your kids developing good study skills?

The ability to focus and work independently—study skills—has been shown to be one of the strongest pre-cursors to later success in school.

K5 Learning is an online reading and math program that helps kindergarten to grade 5 students develop reading, math and study skills. Kids work independently as they proceed at their own pace through K5's 3,000 award winning reading and math activities.

K5's 14-day free trial includes full access to the program and free reading and math assessments. Don't forget to enter MM2012 as your promotional code!

Welcome to February! I hope I found "something for everyone," again!

And for those of you that missed my three-day sale in January, I'll run another in late February! But no, this won't become a monthly habit after that.

Basically, we have a triangle DFE inside a rectangle, dividing the rectangle into various triangles. And, the three areas of fainter color are equal. That is, the area of the triangle DAE = area of the triangle EBF = area of the triangle FCD. (Notice the image is not drawn to scale at all.)

And, we're asked to solve the RATIOS AE : EB and BF : FC.

The solution is posted here.

Vi calls herself mathemusician - and definitely, she's a talented and smart gal! I'm sure you'll enjoy her videos (as long as you can follow her super fast speeaking). Here are some that I enjoyed:

Doodling in Math: Spirals, Fibonacci, and Being a Plant [1 of 3]

(Also, here's a link to learn more about Fibonacci numbers in nature, so you can read about it at a slow pace : ) )

Binary Hand Dance was pretty cool too!

Her series of "mathematical doodling" videos have become somewhat of a viral success. Here's one more:

Doodling in Math Class: Infinity Elephants

You can also see these three videos on my blog.

The formula that this person is using is correct... the formula for compound interest isPlease send me the formula for compound interest and explain line by line.

p(1 + rate)^{3}

What does the 1 stand for and must you add it to the rate of say 10%?

100(1+10)^{3 years}= ???

Obviously I am looking for a basic course?

A = p(1 + r)

but this formula doesn't give us the amount of interest -- it gives us the amount of money you would withdraw after t years. In the formula, p is the original principal, r is the interest rate, and t is the time in years.

However, we cannot put the interest rate in as he did. If r = 10%, then r = 0.1 must be used in this formula. In other words, FIRST convert your percentage into a decimal.

**FREE e-book "All Children Can Be Great Listeners"**

The e-book outlines a simple, 3-step plan for immediately improving any child's listening, and the e-book also includes 12 activity suggestions and 20 worksheets that are designed to be fun and engaging for kids - while helping them hone important listening skills! (This is meant for Kindergarten level).

**Versa Ruler**

Well, this IS something different! A physical ruler that can draw shapes with any angle measure you want. This ruler give you accurate measurements for every side and angle. You can connect sides to form angles, which scale and skew smoothly, and you can lock angles and sides. Unfortunately it's not yet in production. In fact, the project is needing funding... but very interesting!

**The 1-2-3 Song**

Bon from Math is not a four-letter word made this little counting song, sung to the tune of "Twinkle Twinkle Little Star". Hope your little ones enjoy it!
