During the 30-minute lesson, the teacher will spend a few minutes teaching students about how words work. This work is systematic, hands-on, and will increase in complexity over time. Teachers use tools like magnetic letters, chalk boards, and white boards to provide direct instruction of word and letter-sound principles. Choice of letters and words to utilize is based upon data collected during daily lessons noting what students know and are able to do. Lessons follow the common scope of all phonics instruction, but the sequence is individually paced based on each student’s needs. Additionally, word work is done across the lesson in reading and writing, but the focused few minutes is systematic, direct, and student-specific instruction as all effective intervention needs to be.
