A great book to use this month is The Little Old Lady Who Was Not Afraid of Anything by Linda Williams.
Here's a breakdown of how I expand a read aloud into a shared reading and literacy experience:
Here is this month's AAC Calendar! Created by Katelyn Oeser M.S., CCC-SLP and Elizabeth Freund M.S., CCC-SLP, this is a great resource to help you focus on core vocabulary and easy ways to model AAC throughout your day. If you want to be added to the list to receive this monthly, email: email@example.com
Another great resource is the October Writing Prompts calendar created by Lakeshore Learning. You can find this in their "Free Resources" section of their website, along with many others!
