M. C. Escher, Joseph Fourier, Eratosthenes, Euclid, recursion, mobius strip, binary numbers, pi, probability... some stuff just went way over our heads, but Math Out Loud: A Mathical Mystery Tour was definitely fun and zany! (Did you know that Pi is in everything?)
Funny enough, we recently checked out a book called "The Librarian Who Measured the Earth" by Kathryn Lasky. This "librarian" happens to be... Eratosthenes! He's a great thinker of ancient Greece who figured out the circumference of the earth over two thousand years ago. (Told you we're all about ancient Greece these days.) Thanks to Math Out Loud, we now know how to pronounce "Eratosthenes" properly.
I try to keep the heavy subject of Math light at home. No longer do we say "Let's do some Math" in our house; the "M" word seems to inevitably trigger an alarm bell in child and high blood pressure in mom. But we meet with Fred. "Let's see what Fred's up to today."
Fred Gauss is a 3 feet tall boy genius with a flat head, a Professor of meta-mathematics at KITTENS University. He's the protagonist in the 10-book Elementary Series of Life of Fred, the creation of Dr. Stanley F. Schmidt. We're on book 8 of the series, Life of Fred: Honey. It's a good fit for a literary kid like Serena who loves the story format and enjoys the lighthearted humour.
