Students in this self-contained upper elementary classroom are working on phonics, specifically substituting initial consonant sounds. One of the students is using a tile manipulation board. The student is given five letter choices to change the word TOP to POP. The letter choices are also displayed on the student's communication device. With guidance and support from the teacher, the student selects the P to change the word TOP to POP. The video demonstrates effective strategies for engaging students with significant cognitive disabilities in literacy instruction.
