If the image of students feeling bored inside the classroom, wondering what all these numbers and shapes mean and why they are useful at all, feels somehow familiar to you, then we share some common school experience. Now that I am older, I wonder why it has been so difficult for math teachers to actually open this magical world and let us in. And I feel strangely intrigued each time I read about an innovative teaching approach which promises to expose students through playful activities to whole scientific phenomena.
