The document describes the Colour Code English (CCE) technique for teaching grammar and tenses in a visual and engaging way. CCE uses colored shapes and graphics called Pitoshapes to represent verb tenses and allow students to arrange them to check their understanding. It also uses a Timestar coding system to represent different tenses. Research found CCE improved students' grammar skills compared to conventional teaching methods. Teachers reported students found CCE fun, creative, and helped them learn English more effectively.
