图形与几何部分是高年段数学学习的重点,内容上包括平行四边形、三角形、圆形等平面图形的面积计算,还包括长方体、正方体、圆柱等立体图形的特征、表面积以及体积的计算,这里的学习内容不仅多,而且相对集中,学习难度还是挺大的,尤其是空间观念比较薄弱的孩子。如何帮助孩子更简单地、更好地学习这部分内容呢?我想在教学上应该多探寻点适合孩子学习图形的策略,让他们借助策略学习图形。配合学习流程,我为图形与几何部 The graphic and geometric parts are the focuses of mathematics learning in the high school. The contents include the area calculation of plane figures such as parallelogram, triangle and circle, as well as the characteristics, surface area and volume calculation of cuboids such as cuboid, cube and cylinder, The learning content is not only more, but also relatively concentrated, learning difficulty is still quite large, especially the concept of space is relatively weak children. How to help children to learn this part more simply and better? I think we should find more suitable teaching strategies for children to learn graphics, so that they can use strategies to learn graphics. With the learning process, I am the Department of Graphics and Geometry
