Being a maker of educational materials and games, one of the most valuable and useful aspects of my work is when I play with kids and observe how they interact with their surroundings and especially with my creations. This is where I get new ideas and inspirations from.

The Open Geoboard was born this way - iteration after iteration, as the World's first wooden 3D geometric platform for learning, playing, art - based on the idea of the classical geoboard.

Find detailed information about the Open Geoboard in the Bridges 2018 Paper (link above).

Together with children, educators and parents, we create and enhance learning materials and games in my school lab.

Most projects are under Open Design license. FabLab and Maker space ready.

Open Geoboard - 3D Parabolic Curves
16 x 24 x 24 cm
Base: beech plywood; Pegs: high-precision turned beech wood; Rubber bands
2018

Parabolic curves built on an Open Geoboard board with the Cartesian coordinate system in 3-dimensional space using long pegs.The rubber bands are all stretched in straight lines.

Have you noticed, that the parabolic curves kids draw with colourful lines in school on a coordinate system actually look 3 dimensional?

When I saw such a picture I got the inspiration to make it on the Open Geoboard. Casually playing with the rubber bands and trying different peg configurations for the interweaving diagonals in 3D I eventually made this piece.

These forms challenge human senses. From my experience working with kids I observe again and again the owe and enjoyment they feel when they see and touch the strings for the first time.

Open Geoboard - 3D Parabolic Circle
16 x 24 x 24 cm
Base: beech plywood; Pegs: high-precision turned beech wood; Rubber bands
2018

Parabolic curves built on a Open Geoboard board with the polar coordinate system in 3 dimensional space using long pegs.The rubber bands are all stretched in straight lines.

After I made the first parabolic curves in 3D I began looking for ways to create the 3D structure in a circle - and this is the result.

Kids naturally want to make these structures themselves right away and are very proud and joyful when they have made it.

I would love to hear your feedback via the above emails as I am constantly trying to improve the Open Geoboard as a learning experience for kids K-12 and search for collaborations with math professionals. Thank you.
