一、案例描述在教学苏教版数学第三册p23第12题时,课堂生成了一个小插曲,正因这个小插曲,让我对解决问题的教学有了一点思考。首先说说本节课的教学目标:利用1~6的乘法口诀解决生活中简单的问题,并且在具体情景中巩固1~6的乘法口诀。教参中对第12题是这样要求的:先要分别求出小兰家和小芳家各载了多少棵树,然后再比较哪家栽的树多,多几棵。在练习后,还要对求小兰家栽树的棵数与求小芳家栽树棵数的方法进
First, the case description In the teaching of Supor version of mathematics third volume p23 12 questions, the classroom generated an episode, precisely because of this episode, let me have a little thought to solve the problem of teaching. First of all, talk about the teaching objectives of this lesson: the use of 1 to 6 multiplication formulas to solve simple problems in life, and to consolidate 1 to 6 in a specific scenario multiplication formula. Teaching parameters in the first 12 is such a request: First, we must find a small blue and blue Xiaolan family, respectively, how many trees contained, and then compare which tree planted more, how many trees. After practice, but also to find a small blue home trees planted trees and ask Xiaofang home planting trees into
