My daughter, Gretel, is a high school math teacher in Brooklyn, New York. She teaches her students about multiplying polynomials by making quilt squares. The challenge beyond the algebra is having her students measure and cut out the pieces. They make a 12 inch square with sides (x + a) and have to calculate "x" once they have decided on "a." They also have to remember to include the seam allowance. She buys fabric and away they go. After they have cut out the pieces she mails them to me to put the quilt together. I have decided that some of her students are color blind and some of the pieces look like they were cut out with nail clippers instead of scissors. One student aptly names Raphael designed a square that looks like a miniature quilt by itself. Most of the squares are beautiful and the overall effect is stunning. The picture above is the math quilt I made for her class several years ago.
