Sign language classes teach individuals how to communicate using sign language, a visual language that uses hand shapes, movements, and facial expressions. These classes are designed for people of all ages and backgrounds, including those who are deaf or hard of hearing, as well as hearing individuals who want to learn. In these classes, students learn the basics of sign language, including the alphabet, common phrases, and grammar. Instruction often includes interactive activities, such as role-playing and group exercises, to help reinforce learning. Many classes also emphasize the importance of cultural awareness and understanding the deaf community.
