My youngest son, who attended a school that focuses on project-based learning, once brought home a math assignment that centered around 2 quilt blocks. He had to draw his own block with multiple sections, then find the area of the sections, figure out how much fabric he would need, and so forth. I decided this would be a great time to introduce him to the joy of sewing while teaching him practical applications of math, so I let him choose whatever fabrics he wanted from my stash, and he cut out and sewed his two blocks all by himself (with supervision and instruction, of course). He proudly showed his finished blocks to his teacher, who seemed unimpressed, but I didn't care because we had fun!
