7. Learning time and calendar: Students need to learn the hours and minutes on the clock and be able to read simple calendars.
When learning mathematics in the first grade of primary school, parents and teachers should pay attention to cultivating students' interest and curiosity in mathematics, and stimulate students' interest in learning through games and practical operations. At the same time, we should pay attention to consolidate basic knowledge and help students establish correct mathematical concepts and ways of thinking. In addition, students should be encouraged to do more oral calculations and exercises to improve their computing ability and thinking flexibility.
