## Work ordered by math topics

• creations by ​Geometry:

• Congruent triangles using Max Bill paintings:

• Congruences, parallelism and percentages in Max Bill's painting:

• Max Bill, areas, fractions and some more maths - students described the maths behind their different paintings -> see work from German students (in German)
• Areas of rectangles and squares: Using artwork of Piet Mondrian
• Areas of circles: artwork of Sonia Delauney
• Areas of irrgular forms (islands) -see work from Spain
• Living Geometry: working with regular polygons and their properties (Latvia)

• Transformations: Works of Italian students (IIS T Salvini 2D IT and Telecomunications) about transformations Book.
• Transformations in Arts (RO) - GeoGebraBook

​Algebra/arithmetic:

• Square Roots on the Number Line (IT) ->ISSUU book

​Functions:  Creations by Elias, grade 9 (DE)

• Creating flowers with polynomials x², x^3, x^(1/2), x^(1/3), -x^2, ...  • Getting to know different type of functions and approximation of lines and curves in real life objects -> go there
• Quadratic functions, root functions and power function y=ax^n are used to create these wonderful pictures! (see original pictures here) GeoGebra command function(x^2+1,-2,3) draws f(x)=x^2 from x=- 2 until x=3
