Step-by-step explanation:
True or False: Children's self-esteem tends to rise in middle childhood. The answer is True. During middle childhood, which spans from approximately ages 6 to 10, children generally become more engaged in activities such as sports and gain a greater sense of independence. They develop a stronger social network through their interactions with peers, and as they compare themselves positively to others, they begin to form a positive self-concept, leading to enhanced self-esteem. This positive self-concept is crucial, as it is linked to confidence, better academic performance, and a willingness to try new activities.
