MP Graham Stuart officially opened a new community room at Hornsea Nursery School.
Mr Stuart, the MP for Beverley and Holderness, cut the ribbon with help from four pupils on Friday 22 January.
The new room is being used as a teaching space for pupils aged between two and four years old.
It has an interactive area inside which will help children learn language and communication skills.
It will also be available for parenting courses on subjects such as healthy eating as well as for coffee mornings.
To create the new room the school raised £90,000 through fund-raising activities, the school budget and some financial support from the local authority.
Mr Stuart said: “It was an absolute pleasure to be able to congratulate the school on this development and to have the honour of cutting the ribbon to open officially the new room.
“The Head, Clare White, showed me the new 3D Immersive Space and Sensory Experience, which is a great new addition to what the Nursery School has to offer. I could see how much the children enjoyed school with their enchanting performance of songs, story-telling and miming.”
