目标: 一、在排放、拼搭、比赛等操作和游戏活动中学习简单加减运算,初步理解加减意义(求一共多少可用加法,求还剩多少可用减法),熟练10以内口头运算和能按不同特征进行列式运算,知道加法和减法互为逆运算。二、提高学习加减法的兴趣,训练运算能力,发展思维的正确性、敏捷性和灵活性,培养可逆思维能力和应用能力。准备: 实物材料:多用盘一个,彩色数形和符号小方块、几何图形片、珠子、橡皮筋、回形针各若干。过程: 游戏一:找找排排——比谁排得对又多玩法: 一、找找:和孩子一起在黄色符号方块上寻找“+”、“-”、“=”的所在面,告诉孩子:“+”表示“合起来”的意思,“-”表示“去掉”的意思,“=”表示“是”的意思。二、排排:让孩子分别找出同色的数字方块,规定时间在方格盘中排出10以内加减算式题,如彩图1中的五道加法题和五道减法题。
Objectives: First, in the discharge, matchmaking, competitions and other activities and games to learn a simple addition and subtraction operations, the initial understanding of the meaning of addition and subtraction (seeking a total of how many available addition, seeking how many available subtraction), proficiency in oral operations within 10 and can According to different characteristics of the column operation, that addition and subtraction each other inverse. Second, improve the interest of learning addition and subtraction, training computing power, the development of correctness, agility and flexibility of thinking, training and application of reversible thinking ability. Preparation: Physical materials: a multi-purpose disk, color number and symbol small box, geometric figures, beads, rubber bands, paper clips each a number. Process: Game One: Finding a Row - Playing better than one: How to find out: Find the “+”, “- ”, “= ”The face of the place, tell the child: “ + ”means “ together ”means, “ - ”means “ removed ”means, “ = ”means “ yes ”means . Second, the row: Let the children find the same color digital box, the provisions of time within the grid plate discharge less than 10 addition and subtraction formula problems, such as color map 1 in five addition and five subtraction questions.
