In the video, Felisha was asked to share one cookie among four people. What was Felisha's problem solving strategy? Choose the correct answer below. A. Felisha used a fair share model by splitting the cookie into four parts. B. Felisha determined how many groups of one-fourth were in one by drawing a picture. C. She used the invert-and-multiply rule for dividing fractions. D. She did not use any of these strategies.

To determine Felisha's problem-solving strategy for sharing one cookie among four people, let's analyze the options: A. **Felisha used a fair share model by splitting the cookie into four parts.** This option suggests that Felisha divided the cookie into equal parts, which is a common and straightforward method for sharing. B. **Felisha determined how many groups of one-fourth were in one by drawing a picture.** This option indicates that she visualized the problem, which is also a valid strategy for understanding division of fractions. C. **She used the invert-and-multiply rule for dividing fractions.** This option refers to a specific mathematical rule used for dividing fractions, which may not be applicable in this context of sharing a cookie. D. **She did not use any of these strategies.** This option suggests that none of the strategies were used, which seems unlikely given the context. Given the context of sharing a cookie, the most appropriate answer would be: **A. Felisha used a fair share model by splitting the cookie into four parts.** This option directly addresses the act of sharing the cookie equally among four people.
