The Lashon Hatorah program helps the child become an independent translator of the Hebrew language by learning: 


1. The 303 "Shorashim" Root-words

2. The Prefixes/Suffixes


Of the 16,000 words in Chumash Bereishis, 80% are variations of the same 303 root-words. When these 303 shorashim are combined with a working knowledge of the Prefixes/Suffixes, the student will be able to independently translate over 80% of the words in Chumash Bereishis.


We recommend starting with the Climbing Har Sinai Workbook and Vocabulary Flash Cards for vocabulary, and Prefixes/Suffixes Bookmark, Flashcards, and Rabbi Winder's Workbooks for Prefix/Suffixes. These materials will give your child a solid foundation for achieving true reading independence in Hebrew.
