Letter of the Week is a preschool curriculum that I used with our own little one. She's now 11 years old! The curriculum hasn't changed much in the past several years, but it's still just as valuable as it ever was.
Letter of the Week is a 38-week curriculum for teaching preschoolers their alphabet and its sounds.
Scroll down on the above page, which you will find at this link, and you'll see all of the letters of the alphabet. Click on one, "A" for example, and you'll find poems, math suggestions, even field trip suggestions - all related to the letter "A." Also included are scheduling helps.
