The first grade students made these tie dye squares as a sub project. It was so successful, I have since made them with every other grade as well. They began with a small circle of oil pastel in the center of the paper. They surrounded this dot with colorful concentric circles until the entire paper was filled. Then, they took an eraser and dragged it from the center of the page towards the edge. They did this around the whole paper, creating a tie die effect as the oil pastel smudged.
