In this portion of the Homeschool Alliance, members are challenged to include one non-traditional enrichment activity into their homeschools. Themes range from experiments with weather to backyard games to poetry to candle making! Each month's theme has three levels of challenge so you can do the "one star" level and feel pride of success if you don't have time for the more advanced challenges. At the end of the month, reward yourself with a badge!

There's a library with a slew of activities, too, if you want to try some of our previous themes.

Talking Circles

Did you know that March 14 is Pi Day? Even the U.S. House of Representatives has recognized the special mathematical day! 

That's why we're taking March to learn about circles, and, for kids who are ready, to learn about pi, that mysterious number with the decimal "that never ends." Pi is the ratio of the circumference to the diameter of a circle—any circle! 

When you divide out the fraction that represents the ratio, you get 3.1415926535. . . .

The number doesn't divide evenly, and the decimal keeps going infinitely, beyond the ten places shown above. 

Pi is represented by the Greek letter π. 

Many Pi Day celebrations make liberal use of puns and the fact that "pi" is a homophone for "pie." It doesn't hurt that pies are circular, making them a natural for any celebration or study of circles. 

Kids can take part in the fun of Pi Day and learn about circles even if they can't fully understand "pi." Their understanding will grow through the coming years, their curiosity will be piqued, and they will have a connection to a cultural event that makes math fun and accessible. 

Join us in our three One Thing challenges to learn about pi!
