First off, here is a Book of Months for download. Each month gets its own page and on each page, there's a place for holidays and birthdays, as well as a spot for describing words. Have fun!
(Cut out around the border, leaving a strip on the left for the staples! The pages are numbered in the bottom corner for ease!) :)
PS... if this looks familiar, it's because I recreated it from a resource book I saw once. I can't remember the original source, so if you know, please let me know!!
