Very Similar to my Froggy Letter Sort activity. I created this product to help my Special Ed Kinders practice sorting capital from lowercase letters. I've found that by this point in the year, even the kids who know all their letters and can match capital to lowercase letters are struggling to remember which is which, making it hard to teach when to use each type of letter. Hopefully this can help your kiddos as well!
These work well as worksheets or as file folder games with some laminating and velcro.
