My methodology has been empirical, as a fundamental part of academic social projects in schools, forums and spaces for children, youth and foreigners, by university direction. I offer a simple, interactive learning scheme/method for young people and adults. With tools, attractive material, videos and interactions to acquire listening comprehension with: reading, writing and speaking, up to a B2 in Spanish. As an extra of my teaching, to make it even more colorful, I show how fun Spanish slang is at a sociocultural level, as a factor to enhance fluency, confidence, understanding, vocabulary and its different meanings in various cultures of Spanish speakers. The teaching covers its grammatical structure, vocabulary, everyday and technical, rules, tenses, spelling and spelling for integral learning.
