Final answer:
Taking turns when playing with other students and listening to another student who is retelling a familiar story demonstrate self-awareness in an average first-grade student.
Step-by-step explanation:
Two actions that demonstrate self-awareness in an average first-grade student are taking turns when playing with other students and listening to another student who is retelling a familiar story. Taking turns shows an understanding of social rules and the needs of others, while listening demonstrates empathy and the ability to focus on someone else's perspective.
