Somewhere in the world there must be a person turning ten years old on this day, perhaps even someone actually born at 10:10 in the morning. Happy Birthday to you! It’s a special one.

In honor of this day, here is a page from my daughter’s first grade homeschooling main lesson book, Numbers. I don’t know about you, but I am perfectly content to be living in a base-ten number world, with the ten represented by a one followed by a zero. And it was not a foregone conclusion. We could be living in a base-twenty world, like the ancient Mayan, Aztec, Celtic, and Germanic peoples (remnants of which groupings by twenty survive in some modern European counting systems). Or a base-sixty world, like the Babylonians. Or, we could be using base ten but still be lumbering along in lengthy strings of Roman numerals, with nary a zero to be seen. And the computer would never have been born.


Crazy for Math

This is a page of the Improper Fractions lesson from our homeschooling Fractions block. I hope to get the entire book up on the Homeschooling page eventually. For now it serves as an introduction for what I am about to tell you.


Recently a big group of us had dinner at the home of our friends Lynn and Giovanni. The meal ended with everyone playing with math puzzles and games around the dining room table. Lynn, a Math Whiz, owns hundreds of them. For years she was a math instructor and tutor. Then in 1999 she developed a summer Math Camp called “MathTree.” It’s not only for kids struggling with math, but also for kids who can’t get enough and want it included in their summers. (I understand that there actually ARE such children, although none has shown up in my family.)

MathTree has taken off—that first summer there were two locations, and now there are 26 of them (!!!), for kids ages five to teens, all over the Washington metropolitan area. Lynn has developed a hands-on approach using objects, games, puzzles, and real-life experiences. (I was reading the fliers for the camp choices and thinking I might like to sign up myself! except they don’t have my age group.) If you are looking for an unusual kids’ math camp, MathTree might be just the ticket. So I’m putting a link to the website and brochure here. As my husband and I frequently remind each other, Someday Our Children Will Thank Us.
