I did a much simpler quilting activity with my fourth grade students. We called it "Fraction Quilts". Given a large sheet of construction paper, the children had to divide it into 24 equal squares. They were asked to select several of their favorute designs (polka-dots, stripes, flowers, etc.) and create a pattern as they colored in their quilts. The finished quilts had to be described in fractional terms. e.g. 7/24 polka-dot, 5/24 stripes, and 12/24 flowers. I used this activity to give meaning to the terms numerator and denominator. It was a big hit in our classroom!
