《练习7》教案
一、教学内容
《练习7》教案
本节课教学内容选自教材第七单元《分数的乘除法》，主要包括以下内容：
1.掌握分数乘法的计算法则，能正确进行分数乘法计算；
2.掌握分数除法的计算法则，能正确进行分数除法计算；
3.能够运用分数乘除法解决实际问题，提高解决问题的能力；
4.理解分数乘除法与整数乘除法之间的关系，增强数学知识体系的连贯性。
3.成果分享：每个小组将选择一名代表来分享他们的讨论成果。这些成果将被记录在黑板上或投影仪上，以便全班都能看到。
（五）总结回顾（用时5分钟）
今天的学习，我们了解了分数乘除法的基本概念、运算步骤和实际应用。通过实践活动和小组讨论，我们加深了对分数乘除法的理解。我希望大家能够掌握这些知识点，并在日常生活中灵活运用。最后，如果有任何疑问或不明白的地方，请随时向我提问。
2.教学难点
（1）分数乘除法的约分：学生在进行分数乘除法计算时，容易忽视约分步骤，导致最终结果错误。
-举例：计算2/3 × 4/6，学生可能会直接得到8/18，而忘记进行约分得到4/9。
（2）分数除法转换为乘法：学生需要理解除以一个分数等于乘以它的倒数，并在实际计算中熟练应用。
-举例：计算3/4 ÷ 2/3，学生应将其转换为3/4 × 3/2，然后进行乘法运算。
五、教学反思
在今天的《分数的乘除法》教学过程中，我发现学生们对分数乘除法的运算规则掌握程度参差不齐。有的同学能够迅速理解并运用到实际计算中，但也有部分同学在约分和转换倒数这两个环节上遇到了困难。这让我意识到，在今后的教学中，需要更加关注这些难点内容的讲解和练习。
在导入新课环节，通过提出与生活相关的问题，我发现学生们对分数乘除法的兴趣被成功激发，他们积极参与讨论，这为后续的教学奠定了良好的基础。在新课讲授中，我尽量用简洁明了的语言解释分数乘除法的概念和运算规则，并通过具体案例进行分析，让学生们更好地理解。
(2023秋)人教版四年级数学上册《 练习七》PPT课件
角的两条边是射线。
（×）
量角的步骤
1.把量角器的中心与角的顶点重合， 0 °刻度线与角的一条边重合。
2.角的另一条边所对的量角器上的 刻度，就是这个角的度数。
量出下面角的度数。
50°
画角的步骤
（1）画一条射线，使量角器的中心和射线的 端点重合，0°刻度线和射线重合。
（2）在量角器所画角刻度线的地方点一个点。 （3）以画出的射线的端点为端点，通过刚画

∠3＝__6_0_°__
11.（1）你能用一张长方形纸折出下面度数的角吗？ 90° 45° 135°
（2）将一张圆形纸对折三次后展开，可以得到 哪些度数的角？
动手折一折，说一说。
12.选择合适的方法画出下面的角，并说说它们分别 是哪一种角。
10° 45° 60° 90° 105° 120° 180°
角的认识
1.从一点引出两条射线
写出角各部 分的名称。
所组成的图形叫作角。
2.角通常用符号“∠” 来表示，右图的角可 以记作“∠1”。
（ 边）
（顶点）
1
（ 边）
1.填空。
从一点引出两条（射线 ）所组成的图形叫 作角。这一点叫作角的（ 顶点），这两条 射线叫作角的（ 边 ）。
2.判断。
从一点起画两条直线，可以组成一个角。
90°
130°
360°− 90°= 270° 360°− 130°= 230°
15 *右面每个图中的∠1
与∠2相等吗？说明
理由。
3
3
它们都是在直角或平
角中减去重叠部分角
的度数，所以两个图
中的∠1和∠2 都相等。∠1+∠3=90°
∠1+∠3=180°

我们认识了文字，？就可 以读很厚的书，？就可以了解 世界上的事情了。大自然也有 自己的文字。？天上的每一颗 星就是一个字，脚下的每一粒 小石子也是一个字。？
你看，问号像不像一个 钩子？我们读书，就要在头 脑里多装一些钩子，头脑里 到处是钩子，就能把知识钩 进来。
爷爷的书房里挂着 一张条幅，上面写着 “煮书”两个苍劲有力 的大字。小芳感到很奇 怪：书只能读，怎么可 以煮呢？
那些冰块从寒冷的 北方“爬”过来。
旧书不厌百回读，熟读精思子自知。 ——苏轼 读书有三到，谓心到，眼到，口到。 ——朱熹
初读好书，如获良友； 重读好书，透，滚瓜烂熟， 把书熟记于心 。
1.看书就是多多益善，当然是 最好所有的书都要“煮”。 2.中国的书籍，世界的文字浩 如烟海，如果每本书都要煮， 花一辈子都读不完书，所以 并不是所有的书都要煮。
3.煮怎样的书得有选择，感兴趣 的，对自己有用的书要“煮”。 4.对自己帮助不大的只要大概浏 览，不需要 “煮”。
