11月23日,我参加了第五届“蚁谊杯”三市十二所学校联谊活动,共听取了三堂数学课。其中六年级的《用分数表示可能性的大小》一课给我留下了深刻的印象。第一环节:玩游戏(课件出示:摸球游戏,袋子里放了三个黄球、二个红球、一个蓝球。)游戏规则:摸到黄球算老师赢,摸到红球算女生赢,摸到蓝球算男生赢。学生(男):不公平,老师赢的可能性最大,男生赢的可能性太小了。师:是啊,可能性是有大小的。(板书:可能性的大小)
On November 23, I participated in the fifth “Friendship Cup” three school friendship activities in 12 schools, listening to a total of three math classes. I was deeply impressed by the sixth grade “The Size of Possibilities”. The first link: play the game (courseware show: touch the ball game, the bag put three yellow balls, two red balls, a basketball.) Rules of the game: touch the yellow ball count teacher won, touch the red ball count girls Win, boys touch the basketball to win. Student (male): unfair, the teacher is the most likely to win, the possibility of boys to win too small. Teacher: Yeah, the possibilities are size. (Blackboard: the possibility of size)
