Grade K Reading Mastery Language maximizes vocabulary acquisition through direct teaching of word meanings and word relationships. The daily lessons teach students the words, concepts and statements important to both oral and written language. Grade K focuses on the language of instruction—following directions, answering questions, sentence production, comparatives, classification and if-then reasoning. Grade K Language is appropriate for kindergarten and primary school aged children who have not acquired the language knowledge and skills for their age. It is also appropriate for preschool programs and primary-aged students in bilingual and ELL settings.

Español to English is a program that is designed to help Spanish-speaking students enter and succeed in Signature Grade K Language. It provides initial explanation in Spanish, with the students responding in English, thereby giving them the practice they need to become proficient in speaking English. By the end of the program, all instruction and student responses are in English.
