In my last email, I mentioned I was going to add a big section to the site, all about fractions. Well, so far so good. besides the equivalent fractions quiz I mentioned in my last email, there’s a collection of equivalent fractions worksheets, and a bunch of online fractions calculators.

Can you save Peggy (or Peter) the Pegasus from Doom Mountain? Or Get Roger (or Rosie) the Rocket to the stars? You can if you can tell when two fractions are equivalent!

There’s an old magic number guessing trick, where the magician shows asks an audience member to think of a number from 1 to 100, then shows them seven cards. Each card has about 50 different numbers written on it.
As I mentioned in my last email, I planned to make an Advent Calendar for people to download and make. This meant (thinking of and) drawing 25 Christmassy clip-arty icons, and a big picture to hide them all behind.
