This paper describes a tabletop prototype that allows kindergarten children to take the benefits of the new pedagogical possibilities that tangible interaction and tabletop technologies offer to manipulative learning. After analyzing children's cognitive and psychomotorial skills, we have designed and tuned a prototype game suitable for children aged 3 to 4 years old. Our prototype uniquely combines low cost tangible interaction and tabletop technology with tutored learning. The design has been based on observations of the children using the technology, letting them freely play with the application during three play sessions. These observational sessions informed the design decisions for the game whilst also confirming the children's enjoyment with the prototype.
