丰富多彩的生活中蕴藏着大量的数学知识,我们只要善于让学生发现这些知识,并用来解决实际问题,学生将品味到数学的“妙趣横生,其乐无穷”。如在概率的教学中可以引导学生实验:一个袋子里放入一些黑色的棋子,10颗白色的棋子;搅拌均匀,让几个学生从袋子中随意抓出一些棋子,分别数一数白子和黑子的颗数,并记录下来,几次以后,学生自己就发现了规律。利用此项知识,就可以用来估计濒危动物的种群数量,统计一定范围
The rich and colorful life contains a lot of mathematics knowledge. As long as we are good at allowing students to discover this knowledge and use it to solve practical problems, students will appreciate the “magic and endless joy of mathematics”. For example, in the teaching of probability, students can be guided to experiment: Put some black pieces and 10 white pieces in one bag; Stir evenly, let a few students randomly grab some pieces from the bag, count the number of white and sunspots. The number of stars, and record it, a few times later, the students themselves discovered the law. Using this knowledge, you can use it to estimate the population of endangered animals and count a certain range.
