The math of the second grade students begins with Arabic numerals. Students can not only recognize, but also write with wide squares. Math can practice writing Arabic numerals, and the teacher will make clear the position of each number in the grid math book when instructing writing. Therefore, second-year students can still use wide-square math books. Grade two students have just entered primary school, so it is enough to prepare wide squares, pinyin books and math books. In the early stage of cultivating children's study habits and interests, we must read more extracurricular books and read more books. Don't let children brush the questions blindly and brush off their interest in learning. After the third grade, all kinds of disadvantages were exposed, such as being tired of learning and not interested in learning.
