Isabella, who is 5 years old, observes her little brother counting the nine pennies in front of him. He first lines up all the pennies, and then begins to count them, starting from the middle of the line, proceeding first all the way to the end of the line on the right, and then continuing with the left-most penny and counting to the right, ending on the penny directly to the left of the penny he counted first. He counts, "1, 2, 3, 4, 5, 6, 7, 8, 9," and then says, "I have 9 pennies." When Isabella is asked if her brother counted correctly, which response is she MOST likely to make?

Question

Isabella is likely to recognize that her brother arrived at the correct answer, but his method of counting may not be the most efficient or standard way. By starting from the middle and counting to one side before going back to the middle and counting the other side, he may be more prone to errors or confusion. Isabella may suggest a more straightforward method of counting from left to right or right to left without skipping over any pennies.
