Modern Language C uses the Spanish for Children B program from Classical Academy Press. This dynamic language program combines immersion-style dialogues and vocabulary with a study of grammar and the parts of speech as vital tools for the correct speaking and understanding of Spanish. The texts use lively chants to aid memorization of both grammar and vocabulary.There is a distinction between just learning common words and phrases, which is the approach of many Spanish programs, and knowing the language well enough to communicate correctly, fluently, and accurately. All teachers are native.
