Answer:
The response that best illustrates the one-to-one principle is:
D. Simon, who says, "1, 2, C, D, F."
Explanation:
<u>The one-to-one principle focuses on the importance of attributing only one counting tag to each counted object. The counting tag can be a number, or a letter, for instance.</u> Simply put, the child should not repeat counting tags, such as in "2, 3, 3". They should be able to associate one counting tag to one of the objects. Also, <u>they need to be able to coordinate partitioning and tagging. That means the child must be able to differentiate the objects that have been counted from those that haven't.</u> Notice that, among the responses, <u>Simon</u> offered the one that showed this principle. He <u>was the only one who not only counted all the five objects in the array, but who also assigned only one tag to each object. The fact that he mixed numbers and letters does not affect this principle.</u>
