I am a psychologist with a background in deaf and hard of hearing children. I believe the majority of what you would introduce a hearing child applies for a deaf child. Simple modifications, such as signing or enhancing the visual presentation may need to be considered.
For ideas I would suggest puppets and storytelling, cooperative block building, group dancing where following directions is needed and playing games with balls. All of these necessitate visual attending and are great for deaf children to build language development.
