# Blocks, Blocks, Blocks

The last two morning math circles were all about building with blocks and all sorts of spatial puzzles. We had Blokus and Rumis, pentaminoes, Soma cube puzzle, Kapla Mind Builders set and lots of unit blocks. Each of these activities has a number of options, so last week it probably felt a bit overwhelming. But… Read More Blocks, Blocks, Blocks

# Map Coloring and Blokus

These two – Map coloring and Blokus – were the most popular activities at last Thursday’s morning math circle. Other games that I brought were SpotIt – it provides a nice break from problem-solving, but also I hope one day to do a circle that would explore this game deeper. Izzi was another popular puzzle.… Read More Map Coloring and Blokus

# Fibonacci Gerbils

We started the evening math circle with this classic problem: There are 4 apples in a basket.

So we ended up role-playing it with an actual basket… Read More Fibonacci Gerbils

Then we will take a break and, hopefully, start again in the Fall 2017. This circle is quite large. There were at least 12 kids at the… Read More Which One Doesn’t Belong

# The Number Makers

Last Thursday, in my evening math circle (I now have a daytime Thursday circle, but more on this in a separate post), we are continuing to discuss what is math. E. brought a calculator and decided to use it even for simpler problems. That’s perfectly fine with me. A. said that he doesn’t need a… Read More The Number Makers

# Knights and Liars

Last Thursday we worked on the Knights and Liars problems. E, who is generally hard to impress, was thrilled. Turns out, he loves these problems. This was the first time I’ve seen him so enthusiastic, smiling, and looking very happy. For this first Knights and Liars round I chose problems that weren’t too difficult. For… Read More Knights and Liars

# But That’s Not Math!

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!
