The children were given 'math mats' and beans painted to look like pumpkins and ghosts. I instructed the children to create a 'Halloween design' on their math mat using these materials. Creating designs allowed the kids to explore these math materials while having a sense of purpose. The photos below are of the children working on their designs and of their completed designs. After the photos were taken the children had to sort their materials into two piles - ghosts and pumpkins.
