Shelley Lovett shares a great children's fall activity to help develop math skills - leaf size sorting bags. All that is required is three paper bags and some construction paper. Use the construction paper to cut out three different-sized leaves, and to make three labels saying 'small', 'medium', and 'large'. Then simply glue the small leaf and small label on one bag, medium leaf and label on the next bag, etc. To make the loose leaves of the three different sizes they place into the bags, simply cut them out of construction paper (or a harder material if you wish, such as cardstock) using the bag leaves as a template To play the game, just make the bags sit upright and open and have the children figure out how to sort the leaves. A very fun activity for younger children!
