I was reading through some of the posts on a forum that I am a part of, and someone had posted a site with preschool suggestions. The site is called Letteroftheweek.com. There is a section on the site that has each of the letters of the alphabet listed, and when you click into a letter, it has a nice list of activities for that particular letter. There are even long vowel activities available. There is also a story of the week section, sound of the week section, and a preschool scheduling section.
Anyway, I thought I would pass the site along.
