Math in Art An Elementary Festival John Golden Grand Valley State University Credit Where Credit is Due • Susan Walborn, originator and motivator. Instructional leader and teacher extraordinaire. • Barbara Todd, inspirational principal with unhesitating support • Dana Bradt, PTA leader and grant administrator • Amy Archangeli and Joanne Pereira, our great art interns • Teachers and Staff of Aberdeen/Shawnee Math/Tech Academy, a GRPS elementary school, especially Mike Klann and Chris Strevel The Idea Susan’s idea: Students in each grade would take part in a math lesson whose output is a piece of art. Each class would select three pieces to send to a school wide show where the ten best would be selected at a school wide festival. With families invited. And math/art activities to try on the spot. My response: Wow! Second Year Or “How Crazy Were We?” We applied for a community foundation grant to really put the festival on. All of the previous were kept, plus an Artist-in-Residence, a mini Art Fair for the festival night and a mural generated by the students guided by the artist in residence. Goals and Objectives • Reach all students, including those who have not been successful in mathematic • Connect mathematics with art – Get students to ask: “What else does math connect to?” • Increase awareness of art as a possible occupation • Provide opportunity for significant mathematics and real art Artist to Mathematics Some projects were inspired by the artist first. •Alexander Calder •Piet Mondrian •Andy Warhol Calder • Grand Rapids has a large Calder statue (stabile) providing a local link. • Lots of obvious math. Really. – Balance – Variety of shapes Constant Area and the Mean • 3rd graders had to design five shapes with an area of 10 square units. These were cut out and then transferred to heavy cardboard. • Used weights (poster putty on paperclips) to solve the problem of finding a balance point for multiple objects, essentially constructing the mean. After finishing their projects, students displayed them anonymously and evaluated them on a rubric for the math invovlved and for the artistic impact. Universally students were impressed by originality. Mondrian • Connection with jazz • Are you kidding – look at all those rectangles! Golden Rectangle and Fibonacci • Mondrian viewed proportionality as one of the keys to visual harmony. Students investigated the Golden Rectangle by constructing a rectangular spiral. • By studying the data in the rectangular spiral students discovered multiple instances of the Fibonacci sequence. Square added Fifth grade students constructed the rectangular spiral on graph paper, then collected data and found patterns, including the ratio of long to short. Short Long side side 1x1 1 1 1x1 1 2 2x2 2 3 3x3 3 5 5x5 5 8 8x8 8 13 This was the project that convinced us of the artist in each student. We expected students to mimic the spiral motif, but they took amazingly independent and free direction with the projects. Warhol •Repetition with variation •Patterns •Image decomposition into regions This filled a number of gaps – we had no information technology involved, no pop art and no photography before this project was developed. The math link came when I made a connection with a freeware program I use for image editing. There’s a feature that takes the RGB information for color in a picture and permutes it. 6th grade students investigated combinations and permutations, deriving the underlying factorial patterns. The only problem was that they turned out so visually impressive… …that they completely dominated the school wide show! Math to Art Other projects started with the mathematics and led to an art project to investigate. •Shape recognition and use •Polyhedra •Fractals Shape Recognition For a project accessible to kindergardeners in terms of math and art. Shape recognition despite orientation and size was perfect material and Susan had the idea to use them to make… Students chose a shape for the face, painted it, and then chose shapes for the features. Shapes of the same type had to be colored the same color. Artistically they investigated the emotion their masks showed. How do kindergardeners vote? Polyhedra • 3rd graders investigated polygons, then extended the properties to three dimensions. • They used polytiles to design a sculpture, then partially disassembled it to make a plan for a net. • Students then laid polygon templates out (with a larger scale) to make a net for a cardboard sculpture. • They folded up the cardboard net to make a sculpture. Aside from the sculpture aspect, students learned about graphic design, analyzing how packages are decorated with repeated geometric designs. Fractals Susan had already been investigating origami fractals with several classes, but felt strongly that festival projects should not overlap with other work. Investigating fractals led us to the idea of Sierpinski carpets – connecting immediately with textile art. 4th graders investigated •recursion, •generation by motif •exponential number patterns Other! Students learned about Jackson Pollack and created abstract works based on topology and the Jordan curve theorem. 2nd graders looked into kaleidoscopes and investigated rotational and reflectional symmetry. Then they used MIRAs, precut shapes from origami paper and hinged mirrors to make their own kaleidoscope design, which was displayed in embroidery hoops. Frieze! 1st graders worked on an ancient art form already loaded with math – friezes. They studied translations and rotations as well as several types of visual patterns.
