Math in Art Festival Math in Action for 2003 Festival website: faculty.gvsu.edu/goldenj/mathinart.html John Golden goldenj@gvsu.edu Credit Where Credit is Due The Math in Art festival is the brainchild of Susan Walborn, math specialist at Aberdeen Math/Tech Academy, an open admission citywide school in the Grand Rapids Public School system. In addition to being an excellent math teacher, Susan is an artist representative and co-owner of a gallery/stationary store in Grand Rapids (Yours Truly on Cherry St. near Lake.) She was looking for a school wide festival to end the year on a positive note, after long struggles with possible school closings, etc. The idea of the festival quickly took off and was adopted by the school, students, parents, teachers and administration. Susan brought in Joanne Pereira, an art intern from the Maryland Institute College of Art, who was invaluable. Without wanting to exclude anyone by singling out another, Dana Bradt did phenomenal organization of parents and activities for the Festival Day. The support from Principal Barb Todd was also amazing. This year the festival is on again, with funding support from the Grand Rapids Council of the Arts, an artist in residence, and actual compensation for the student intern. This year Mike Klann is the artistic director (and a 2nd grade teacher), Amy Archangeli is the art intern, Dana is the administrator (and PTA president) and Susan is the mathematics director. We’re working in cooperation with Chris Bengston, the technology specialist. (I'm either a co-mathematics director or a consultant. I can't remember the title!) What it is The idea is to have a combined math/art lesson that has as an end product a piece of art. Classes then voted anonymously on their pieces, choosing the top three to go to a school wide art show to be held simultaneously with a festival day. On the festival day, attendees voted on their favorite works from the entire show, and then the top honorees were given awards and trophies. Also at the festival were over 20 booths where students and family members could make an art/math project on the spot, such as tessellations, mosaics, kites, etc. The 2002 festival was very successful, with over 300 students and family members returning to the school in the evening. Susan and/or I designed all the math lessons, with considerable input on the art content from Joanne. The lessons taught included: Grade Math topic Art product (topic) Kindergarten Motions Friezes First Probability Abstract line drawing Second Reflections Kaleidoscopes (color connotation) Third Polyhedra Sculpture (graphic design) Third Isometric drawing Isometric Building Pictures Fourth Symmetry Quilting Patterns (adapted from Everyday Math) Fifth Golden Ratio, Fibonacci Numbers Geometric abstract collage (Mondrian) Fifth Fractals, Pascal's Triangle, Patterns Fractal triangle patterns Sixth Fractal patterns Fractal carpet (texture) © 2002, 2003 John Golden, Susan Walborn Permission granted for educational use. Many of the lessons above had detailed lesson plans made as part of a preservice teacher education class (Math 322). Those are available at the festival website, along with many pictures and a copy of tonight’s handout. We have some new mathematical topics being developed for the 2003 festival. These will likely include the Jordan Curve Theorem and Jackson Pollack, design and mathematics of Celtic knotting, logical sequencing and flip books, reflectional symmetry and stained glass window design, and the four color theorem with map design. As always we strive for both exciting math and art, with a high quality end product. Today On the following pages we will zip through some of what the students did for second, third and fifth grades. Fifth Grade – Golden Ratio On the next page is a section of square grid paper with an x marked in one square. We are going to create a rectangular spiral by adding a square to the long side of the rectangle, and then repeating this step in a clockwise fashion. Students recorded data in a grid like below and found patterns in the results. The art project then involved using squares proportional to the patterns below, first making a plan to scale, and then making a large scale collage according to their plan. They had proportional square pieces to trace and cut out for the final collage, but had to measure out by hand the squares for their plan. Since the art lesson included a presentation on Mondrian, we were expecting some imitation of him. But the students were completely original, ambitious and impressive.

Second grade -- Kaleidoscopes The lesson began with students looking into actual kaleidoscopes, observing what they saw. This included things that indicated the reflectional symmetry. We then disassembled one of the kaleidoscopes to help complete the picture. Students used hinged mirrors to see how reflections of a few shapes created a full circle with many of the patterns they observed. On the following page there is a circle with a wedge indicated. Fill in the wedge with 3 or 4 simple geometric shapes. (The students made their own wedges through folding and used precut colored pieces of origami paper with many varieties of shape.) Using the MIRA, reflect over side A of the wedge, sketching in the reflections of your shapes. Include a sketch of the reflection of line A. Now reflect your reflected shapes over the reflection of side A. Continue the process until you are back to line B. When the MIRA is placed on line B, the last drawn shapes should be reflections of the original. The students did this on tracing paper mounted on embroidery hoops. Hung in a window, this produced the effect of the kaleidoscope. These were among the most striking pieces of the festival. © 2002, 2003 John Golden, Susan Walborn Permission granted for educational use. Third Grade – Pascal meets Sierpinski This lesson began by having the third graders generate Pascal’s Triangle, after deducing the pattern the instructor used to fill it in. They did quite a few rows… as you may take the time to do now! For you we’ll make a special challenge, however. After the sixth row (the one beginning 1, 6, …) just fill in the rest of the triangle with E if the number would be even and O if the number would be odd. The next page has a Pascal’s Triangle cheat sheet, if it is desired. Shade in the squares that have an odd number. After the students filled in their numbers, and checked for correctness, they chose two number patterns of their own. Examples were ends in ___, had two of the same digit, multiple of ___ and other more creative offerings. They then had to color in a Pascal’s triangle by coloring their one pattern one color of their choice and their other pattern another color, with a predetermined rule for what they would do if a number fit both. To add some creative options, they had a number of different pyramid styles to select from. Overall, this was not as artistically impressive as some other projects, but was one of the mathematically richest. The pattern recognition, determination and discovery were really deep, and when the class pooled their results they had covered many of the classic patterns of upper elementary mathematics. © 2002, 2003 John Golden, Susan Walborn Permission granted for educational use. Each of the grids was a full sized sheet of paper, and there were 10 varieties of grids available.
