一天,几个学生到我办公室对我说:“黄老师,您能否带着我们研究勾股定理,因为我们在计算直角三角形斜边的长度时需要用到勾股定理,但我们又弄不清楚勾股定理的真正意义。”基于学生的需求,我答应了他们。勾股定理是八年级的教学内容,要让小学生做研究,必须建立在直观图形中,让他们通过形象思维建立表象,从而建立勾股定理的模型。
One day, several students went to my office and said to me: “Teacher Huang, could you take us to study the Pythagorean theorem because we need the Pythagorean theorem in calculating the length of the hypotenuse of a right-angled triangle, I do not know the true meaning of the Pythagorean theorem. ”Based on the students’ needs, I promised them. The Pythagorean Theorem is an eighth-grade teaching content. For primary school students to study, they must be based on visual graphics so that they can create representations through visual thinking and establish a model of the Pythagorean Theorem.
