I tried these great sorting activities I found on a wonderful Montessori blog called Chasing Cheerios. http://www.chasingcheerios.blogspot.com/ She always has wonderful activities for her children to do. Sorting with colors, letters, numbers, sizes, etc. I did this with numbers where I had cards with the numbers 0-5 written on them and Zeke had to put that number of cars there. He did really well with little help. Then I had foam numbers and he matched the foam numbers to the cards. He did that with no help at all. Last we sorted his toys with these letter cards. It was lots of fun and we sounded out different letters. This will be a regular part of our learning!
