As you study community helpers, have students add them to their personal Community Helpers Alphabet booklet. 

If you need an alphabetical list of community helpers for your little ones to choose from, be sure and check out my Community Helpers List From Astronaut to Zookeeper, where I list over 300.

If you don't study community helpers as a theme, but want to make an alphabet booklet using other words, I have also included a generic alphabet cover and first page.
