For one week, Elle and I focused on leaves. The first day we went on a leaf walk in our backyard and gathered all types of leaves from our trees. After we had gathered a sack of leaves, we took them inside and organized and sorted them by color.
With both options, she had a great time and loved practicing her colors on both the real and paper leaves. On another day, we used the paper leaves to make up "falling leaf" songs. As we sang the songs, we threw the leaves into the air to let them fall to the ground. Baby Liv found this quite entertaining.
