最新一年级上册我说你做教案

《我说你做》教学设计

教学内容

北师大版小学数学教材一年级上册第72—73页“我说你做”。

教材分析

“我说你做”是一个可供两人玩的搭积木游戏，是在学生认识长方体、正方体、圆柱、球的基础上安排的活动课。这一活动一方面是巩固学生对立体图形的认识，另一方面则是为发展学生表象思维提供了一个载体。学生在根据指令进行摆放物体时，首先需要在头脑中有立体物体的表象，至于放在哪里合适，则需要熟悉物体的特征。通过触摸、拼摆等活动，培养学生初步的空间观念。

学情分析

学生通过前一节课的学习，对长方体、正方体、圆柱、球已经有了一定的感性认识，知道这些几何体的名称并能进行识别。

教学目标

知识与技能：

使学生在观察、操作活动中，获得对简单几何形体和图形的直观经验，发展学生的空间观念。

过程与方法：

能用长方体、正方体、圆柱和球拼出自己的图形，能清楚地向他人说明自己拼图的内容和方法。

情感态度与价值观：

能正确评价他人的作品，培养学生的审美情趣。

教学重点、难点：把简单的数学问题用游戏放之于现实情境中应用。

教法：实验法。

学法：实验探究。

教具准备：一些简单的几何体。

教学过程：

一、问题情境：你知道了四种物体名称，我们来研究一下它们的数学问题。

你想用什么方法来研究？（分组讨论）

二、建立模型

1、分组研究讨论。

学习要求：（1）讨论这些物体摆放的不同。

（2）准备向全班同学介绍你们的研究结果。

2、汇报交流，初构模型。

师：物体间位置可以用上下左右来分析，在小组中交流、汇总的基础上讨论出结果，明确空间关系。全班确定一下其空间位置关系。

3、情境迁移，再构模型。

情境呈现：几个几何体积木。

你说我摆，同桌互相进行游戏，随着空间位置关系确立，其积木的个数可以随之增加，说和摆的身份可以变化。

三、拓展应用

1、说一说，写一写。

让学生仔细地观察，想一想哪些物体的形状是长方体（长），正方体（正），圆柱（圆），球体（球）。再同桌互说，并用单个汉字写下来。再用空间位置关系来说。

（其形状只要大致正确即可）

2、看一看，填一填。

让学生自主完成。

3、摸一摸，说一说。

这是一个游戏，可以让学生把操作活动与表达结合起来，可以是学生摸一个物体并说出它的名称，也可以结合名称再支摸出相应的物体，这一活动可以分组进行。4、看一看，数一数。

对本题的解答有一定难度，可以用搭积木的方法先协助解答。

四、总结回顾

1、这节课你学了什么？

2、前后的关系在生活中应用。

五、板书设计：

我说你做

球、正方体、圆柱、长方体

Dear Nancy,

I am in Shanghai. It’s Thursday, November 5th. I really have a 11day. At 8:00,

I have science. I like science because 12interesting. Then at 9:00, I have math. I

don’t like math. It’s 13and boring. At 10:00, I have history. It’s boring, 14 . At

11:00, I have music. That’s my favorite 15! Music is relaxing. I 16my music

teacher, Mr. Smith. He is very nice.

I eat lunch at 12:00. After lunch, I have P.E. at 13:00. I like P.E. 17it is fun.

But our teacher is very strict and I’m usually very tired. My 18class is at 15:00.

After class I play basketball for an 19 . My dinner is at about 18:00. Then I go to the

art club (俱乐部). At about 20:00 I do my homework and 20it at 22:00. At last I

go to bed. What a busy day it is!

Yours,

Lucy
