How does Sails help teach high frequency words?
Sails is structured into sets of four books. Each set of four concentrates on one main high frequency word, ensuring plenty of consolidation of that word. Additionally, most books contain several other high frequency words as well, meaning that, even though Sails in only Pink level, the majority of NLS high frequency words are covered. There is also a high frequency word check page for extra practice in every book.
