This class art project can be made overtime or in one block. The students draw or glue on objects to their craft squares to make as many arrays as possible for their number. Then they color the border of their quilt square red for odd or blue for even depending on the number on their square. I have done this activity to ways. One is individual where the students each make 4-6 squares over the course of a week and then at the end they glue them together to make their own quilt. The second way is making a class quilt where each student is giving one or 2 squares to complete and we put it in the hallway as a class work of art. You can also just use these squares to model the idea of arrays as part of your direct instruction or morning meeting activities and then display on your math bulletin board. Enjoy and please leave feedback.
