Our Thursday evening math circle is back (after a longish break). So far there are 4 participants – M, A, K, and E. Indeed, math is what you MAKE of it! (will wear this T-shirt to the next meeting for sure). I started off with some insight problems from Bright, Brave, Open Minds by Julia… Read More But That’s Not Math!
This Thursday was the second meeting of our Mazes… math circle. Fortunately, everyone was well and we had a full house – RB, L, and E were back and A and V joined us. A’s younger brother, M stayed as well. To begin with we did a bit of a review – looked at the collection… Read More Mazes, Maps and Moebius Strips 2 – More Islands

Since then we’ve been using them pretty regularly for all sorts of activities: Math Manipulatives Light, small and colorful, these are excellent counters… Read More The Owls and the TIE Fighters
I don’t remember if I mentioned it before, but for the last few months Rocket Boy has been obsessed with building a cardboard arcade. It all started with watching (more than once) the Caine’s Arcade video. Then he started building. And soon the guest room (aka LEGO room) was taken over by cardboard. Since then he… Read More Cardboard Arcade Roll Out
I was going to do a class for 6-10 year olds today. The plan was to explore symmetry with snowflakes. But nobody signed up and the class got cancelled.
