We are interested in creating rich, multi-sensory experiences for our children early on. We want to introduce them to the complex and exciting world around them. Everything can be a learning tool, a rich toy, and a conversation starter.

  • Snowflakes are examples of fractals and an invitation to explore symmetry.
  • Sliced fruit illustrates integrals and derivatives.
  • Floor tiles form beautiful tessellations.

Author – Julia Brodsky writes: My 6 year old daughter was interested in math, so I began looking for math circles for her, and found none in our area. I wrote to National Association of Math Circles and asked them whether they have any materials for young children. Their reply was: “No, but if you develop something, please share with us!” That’s how it all started. My teaching experience includes homeschooling two of my kids, raising a special needs child, several years of private and public school teaching experience, as well as teaching college students and NASA astronauts. But I love teaching young kids the best! Julia’s site.
