通过《圆形与圆形物》一课的学习,使学生认识圆物(包括圆、椭圆、半圆),并能联想生活中的圆形物,在圆形的基础上把它们画下来,从而培养学生的观察力、想象力。在圆形的基础上画出圆形物是本课的难点,同时渗透着以后学生应遵循的绘画步骤,即在基本形的基础上画出各种物象。为此我在教学中采取了实物演示、教师范画、学生学画等 Through the study of “Circle and Circle”, students can recognize the circle (including circle, ellipse and semicircle), and can learn the circle in life and draw them down on the basis of circle Cultivate students' observation and imagination. Draw a circle on the basis of the circle is the difficulty of this lesson, at the same time infiltrated by the students should follow the painting steps, that is, based on the basic shape to draw a variety of objects. To this end I have taken in-kind teaching in the teaching, teacher Fan painting, student learning painting
