Class 5 typically refers to the fifth grade in the educational system, which usually includes students aged 10 to 11 years old. In this grade, students build on foundational skills in subjects like mathematics, science, language arts, and social studies. They often engage in more complex projects and begin to develop critical thinking skills. In many countries, Class 5 serves as a transition year, preparing students for middle school. Curriculum topics may include fractions, ecosystems, and historical events. Assessments often include tests, quizzes, and group projects to evaluate students' understanding and collaboration skills.
