This is a Notebook file for Smartboard. Kids can sort images of animals into two boxes - one for animals with a long vowel sound in their name, and one for animals with a short vowel sound in their name.
Note that it was made in version 11 of the software - I make no promises that it will work in earlier versions, but I don't see why it wouldn't.
(Kinda copyright stuff...)
Animal images are from a very old ('07) version of "PIcs for PECS". I edited them to get rid of the matching word and added the transparency. The box was from a Google search and modified by me so that the animals can go inside it.
