The purpose of The Winston Grammar Program is to help students understand the structure of language and comprehend the principles of traditional grammar. The Winston Program uses innovative means to achieve conventional ends. It does away with the traditional grammar textbook, lecture approach, and heavy emphasis on memorization. 
Instead, it gives students a set of color-coded clue cards and a book of exercises, which together generate multi-sensory activities:

  Moving 
  Seeing 
  Hearing 
  Speaking

Repeated use of the cards results in the students' acquisition of knowledge with little or no memorization required.
