I have written a book entitled:
Increasing Language Skills of Students From Low-Income Backgrounds: Practical Strategies for Professionals (2013). This is available from Plural Publishing in San Diego.
I have also created a continuing education program for speech-language pathologists entitled Increasing Oral and Literate Language Skills of Children in Poverty (2014).
My youtube channel has examples of how to read and interact with children to build oral and literate language skills.
The Sacramento State Literacy Connection contains many suggestions (written in different languages) for those who interact with children to build their literacy skills.
