在小学数学几何初步知识的教学中,常常遇到一些要求学生作图的练习题。这些用指定的工具画指定的图形的练习,可以帮助学生进一步理解这些图形的特征,培养初步的空间观念,同时形成几何作图的基本技能,为今后的学习打好基础。所以,在教学中重视并加强这些作图题的练习和指导,对于提高学生素质,深化教学改革,有着重要的意义。 In primary school mathematics geometry initial knowledge of teaching, often encounter some exercises require students to drawing. These exercises of drawing specified figures with designated tools help students to further understand the characteristics of these figures, cultivate preliminary ideas of space, and form the basic skills of geometric drawing so as to lay a solid foundation for future study. Therefore, attaching importance to and strengthening the practice and guidance of these drawing questions in teaching plays an important role in improving the quality of students and deepening the teaching reform.
