数学学科具有一定的抽象性和逻辑性。为了让学生更高效参与数学课堂学习,老师们常常通过巧妙设计多样性的活动,引导学生参与活动,在活动中达成课堂学习的目标。学生在活动中,理解数学概念,学会分析和解。本文以《和的奇偶性》一课为例,谈谈课堂活动设计与实施的一些思考。【教学片断】探究活动一师:同学们喜欢玩游戏么?(出示扑克牌)想不想用它玩个游戏?玩游戏,有规则的。大屏幕出示规则:(1)抽两次扑克牌,将两次牌上的数相 Mathematics has a certain degree of abstraction and logic. To enable students to participate in math classroom learning more effectively, teachers often guide students to participate in activities and achieve the goal of classroom learning through clever design of diverse activities. Students in the activities, understanding of mathematical concepts, learn to analyze reconciliation. This article takes the lesson of “Parity and Harmony” as an example to discuss some thoughts on the design and implementation of classroom activities. [Piece of teaching] explore a division: students like to play games? (Show poker) Want to use it to play a game? Play games, there are rules. The big screen shows the rules: (1) pumping two poker cards, the number of cards on the card twice
