This is a great project for the 3rd graders. We get a small plastic cup and cut it 3 times and try to get them evenly spaced. Then we start weaving with our yarn and go inside the cup and then outside, Let them know its just a easy pattern. And from there they just continue till they fill the outside of the cup with yarn. I have done this before with bigger cups and that turned out pretty good too, but it goes a lot easier with the smaller cups. And if you make a triangle in the middle of the cup you are doing it right.
