Youngsters at East Whitby Academy joined others from across the county signing and singing to help vulnerable deaf children and adults.
The children are taking part in sign2sing, a sign language event organized by the charity SignHealth.
The pupils have been learning the words and British Sign Language (BSL) signs to a song called Together, which was specially written for the event.
They performed the song at school last week.
Headteacher Simon Smith said: “Brilliant to see our inclusive school singing and signing together - a real community.’
