Blending is important for students to understand how sounds fit together. When an OG instructor is doing the blending drill, they put 3-4 packs of the phoneme cards out. Each card has a sound that the student can already read. The student needs to say each sound in order, pointing as they go, and then blend them together (some instructors use the word “scooping”). The instructor can use nonsense words, but they should never break a spelling rule, because this is pure decoding practice. For example, I wouldn’t want to see a nonsense word like “kandy”, because the letter k is usually only followed by the letters i or e. Sight words should be drilled separately from this part of the lesson.
