    Here we will list all work with a short descriptions and links to subpages that contain 2-3 different contributions (otherwhise pages get too long). Sometimes we also announce future projects to share work or let students cooperate or have ideas for continuation by another country.

    Project 1:

    • Artwork of 10 years old students having to do with Fibonnacci circles and colours of Piet Mondrian (GER) 
    • ​RO students(7 grade) can make in ggb design and calculate the areas..., percentages between colors...or can create problems on the designs.
    • CRO students (7 grade) can calculate the areas and the ratio between areas.
    • POL students (6 grade) program the Ozobot - "Ozobot Bit -The Fibonacci Traveler"
    • LV students (5 grade) Polygon art using Golden Ratio inspired by Piet Mondrian


    Project 2:

    • Ying Yang, Geogebra and wonderful pattern  (GER)
    • Wonderful patter in Geogebra - 6 grade (CRO)
    • The string of odd natural numbers in triangles and squares (RO)


    Project 3:

    • Multiplication table and numbers in the circle (CRO)
    • Students (grade 5 mainly) can continue and report about their discoveries  (GER)


    Project 4:

    • Art and math discoveries with circles and polygons constructed with GeoGebra (GER)
    • Learning math area and perimeters on polygones and circles made by german students (RO)

    Project 5:

    • same Polygons and different circles and a surprise (GER)
    • RO students create a tool for German students
    • Students will constructively demonstrate this rule on paper (CRO)
    • Construct the circumcircle  of  a  triangle and construct the incircle of a triangle (IT), proof of the Japanese theorem for cyclic polygons


    Project 6:

    Project 7: star project

    • RO students  construct tool collection for different stars 
    • GER students fold and cut out, make stitch art and construct with GeoGebra
    • CRO students create christmas cards with stars
    • GER students learned from RO students how to create star tools and create christmas cards


    Project 8: Rectangles, squares....

    • Polygon art using golden ratio inspired by Piet Mondrian (LV)
