Final answer:
The teacher led the students to scrape with their hands to the sound /k/ to engage tactile and kinesthetic learning, helping to solidify the connection between auditory stimuli and physical sensations, and to support diverse learning styles. The correct option is B.
Step-by-step explanation:
The reason the teacher had the students scrape with their hands when they heard the sound /k/ in a word is B. To engage tactile and kinesthetic learning. This method is beneficial for helping students make associations between physical sensations and auditory stimuli.
By engaging in a physical activity that corresponds to the sound they hear, it helps reinforce their understanding of the sound and the way it is produced within different words.
For example, when students hear the /k/ sound in "school" or "blackest," the physical activity of scraping can solidify the connection between the sound and its various spellings like , , , , or .
Additionally, this approach supports the idea that children learn in diverse ways and those who are kinesthetic learners particularly benefit from tactile experiences, which help improve their phonemic awareness and reading skills.
