All children develop and learn at different rates. In general, the pattern is similar to how the child learned his first language. During the first year, the child builds a base of vocabulary, learns the patterns of the language and understands 80-100% of the spoken language. He may begin using single words and short phrases and will likely sing the songs he has learned in school. During the second year, children add vocabulary and begin to use the language naturally, responding and participating in class in Spanish. After two to three years of exposure, they typically begin to think in Spanish without translation, communicate their thoughts, and carry on conversations in Spanish with a native accent.
