The letters covered include the “scene” (س) and its twin “sheen” (Ø´), followed by “sod” (ص), with explanations on how they are written in various word positions. The teacher emphasizes the differences in pronunciation between similar-sounding letters, using visual and auditory cues to aid the learning process while integrating these letters into different word positions for clarity.
