教学《刻舟求剑》时，一些学生对掉剑人的想法和做法错在哪里难以理解，可制作下面教具，帮助学生理解课文内容。课前在小黑板上贴出画有江水的图，用泡沫塑料刻只小船，在船的背面钉若干颗图钉，再用硬纸板剪一个人的模型，腰间插一把能掉下的纸剑，用透明胶带把人粘在船里。 Teaching “carve the sword”, some students think the wrong sword and the wrong way where it is difficult to understand, you can create the following aids, to help students understand the text. Before class, paste a picture of the river with a small blackboard, carve a boat with foam, nail a few thumbtacks on the back of the boat, cut a man's model with cardboard, and insert a drop of paper Sword, with sticky tape sticking people in the boat.
