I am very proud of my 6-year old and the math discoveries he makes. Two days ago he came up with a proof that zero is an even number. Yesterday he built something he called “a square that has volume” (a cube), then connected 4 of them into a larger cube. And today, well before […]
These are notes about a math circle for kids ages six to ten. Thank you for your write-ups, Kristin and Sally! All photos are in the set on Flickr. This time, I talk about several activities that did not work as I hoped. In hindsight, I think I know how to fix the experiences, and […]

Reverse costumes Doctor Popular on Flickr says this really happened. I love it because reversals are challenging, and often clever. […]

The main goals of activities were to contrast linear and non-linear growth, and to approximate curves with straight lines. Children’s activities brought my attention to three other ideas: consistency of patterns; differences; and measurement. Here are all photos from the Circle. […]
