Mathematics is usually taught at ...
Correct Answer
B. School
Explanation
Mathematics is usually taught at school because it is a fundamental subject that requires a structured learning environment. Schools provide the necessary resources, such as textbooks and math manipulatives, as well as qualified teachers who can guide students through the curriculum. Additionally, schools offer opportunities for students to collaborate with their peers, engage in group activities, and receive immediate feedback from their teachers. This facilitates a comprehensive understanding of mathematical concepts and promotes critical thinking skills. Teaching mathematics at home, a museum, or a restaurant may lack the necessary structure and resources to effectively teach the subject.
