Final answer:
To provide practice with a given sound-symbol correspondence in a lesson, it is recommended to use 15-20 words. This range allows for adequate practice and reinforcement without overwhelming students, facilitating the learning process. Option b is the correct answer.
Step-by-step explanation:
When teaching sound-symbol correspondence, the goal is to provide enough examples for students to recognize and practice the targeted phoneme-grapheme relationship effectively. Working with 15-20 words is generally considered sufficient for practice without overwhelming students.
This range allows for adequate repetition and reinforcement, which can facilitate the internalization of the association between the sound and its written representation. Furthermore, it enables instructors to present a variety of word contexts, enhancing generalization of the skill. Fewer than 15 words might not provide enough practice, while more than 20 could lead to cognitive overload.
Importantly, the practice should include diverse examples, including words where the target sound appears in various positions (beginning, middle, end) and different types of words (nouns, verbs, adjectives, etc.). Given that letters and sounds can function differently across words - with some letters working together to spell a single sound or not spelling any sound - a rich selection of practice words can help students learn to navigate these complexities.
In summary, for practice with a given sound-symbol correspondence within a lesson, using 15-20 words is recommended. This number is substantial enough to promote learning without causing fatigue or boredom. It's an approach supported by educational research and pedagogy for effective phonics instruction.
