Graphically, because gossip is strictly arranged and combined, the logic of thinking can't be changed just like the axiom in math class, so it can be considered as training the arrangement ability of thinking combination. Eight trigrams originated from China's ancient Hetu and Luoshu, and spread to Fuxi.

Graphic ability training

1, cultivate students' analytical and comparative ability. Through the teaching of rectangle, square, quadrilateral, triangle, trapezoid and combined graphic area, students are guided to compare the similarities and differences of these graphic solutions in groups, so as to effectively cultivate their analytical and comparative ability.

2. Cultivate students' general reasoning ability. For example, when teaching triangle area calculation, students should calculate the area according to the method of several squares, and then ask questions. Is there an easier way? So as to guide students to think, and on this basis, the calculation formula of triangle area is abstractly summarized. So as to cultivate students' abstract generalization ability.

3. Mathematics textbooks embody logic everywhere. Teachers can't talk about mathematics knowledge only on the surface of textbooks. Only by strengthening the basic knowledge, paying attention to cultivating students' initial logical thinking ability and consciously and purposefully excavating the logical factors of teaching materials can students' logical thinking ability be continuously improved.
