In spring 2017 I started and ran the Espoo International School Math Club. It is an after-school activity for kids in elementary school. We engage in a variety of activities covering all kinds of math that is very different from what is found in the regular curricula. I am continuing the club in autumn 2017.
For each weekly meeting I write a blog post with the description of the activities we did, a short overview of the mathematics, links and apps. There are also additional activities to try at home that often will be fun for the whole family :)
Here is a direct link for the activities from spring 2017.
