"They used to be..." A-Z letter pack includes pages for each letter and an example to show students. 27 pages total!
A fellow teacher gave me something like this years ago, but I couldn't find the source! So, I recreated and tweaked the original a bit. :)
Students use their creativity to create a new picture (using existing letters) and complete a sentence about it. Use this for introduction of new letters, creative writing, or work into your themes.
