The benefits that ICT brings to education are becoming more evident every day. For teaching of Mexican sign language, it is one of a great benefit to have tools that support the teaching-learning processes. This paper presents a tool to teach children with or without hearing disabilities the Mexican Sign Language in order to communicate in a successfully way to get along and play nicely through the language. To guarantee the quality of the tool, it relied on Software Engineering, specifically on the agile Extreme Programming methodology. The main result is the tool named "Manos que hablan"; with it, through games, it is sought to achieve meaningful learning in the Mexican Sign Language in children with or without hearing disabilities of preschool age; at the same time, a better integration and inclusion is sought inside and outside the classroom with people with hearing disabilities. The tests carried out on children get positive results, achieving the validation of the tool. This tool is accessible through an electronic device connected to the Internet, which the child with or without hearing disabilities could play to learn the Mexican Sign Language.
