1、认识升和毫升冀教版数学四年级上册第一单元1、在实际操作活动中了解容量的概念，认识“升”和“毫升”，会用字母表示“升”和“毫升”。2、认识测量工具量杯和量筒，会读量杯和量筒上的刻度。3、在实验活动中获得愉快的学习体验和数学活动经验。教学目标哪个杯子盛水最多，哪个杯子盛水最少？比一比：下面两个杯子哪个盛水多？ab方法一1.把b杯子装满水，倒入a杯子中……2.把两个杯子都装满水，分别倒进两个一样大的杯子里。方法二结论：a杯子盛水多。两个杯子大小不同，盛水的多少也不同，杯子容纳水的多少，就是杯子的容量。比一比：下面哪个瓶子装的饮料多？说一

2、说可以怎样测量？ab除了把两瓶饮料分别倒进两个一样大的杯子里之外，想一想，还有什么方法？认识量筒和量杯。量筒和量杯有什么区别？区别：量筒口径上下均匀，所以刻度均匀；量杯口径下小上大，所以刻度下疏上密。认识升和毫升。计量液体，如汽油、饮料、药水等，用升和毫升作单位。升用字母“L”表示，毫升用字母“mL”表示。把两个瓶子中的饮料分别倒入同样的量杯中量一量。a瓶饮料多b瓶饮料少归纳总结1.容器中所能容纳液体的多少，就是容器的容量。2.计量液体的多少，用升和毫升作单位。升用字母“L”表示，毫升用字母“mL”表示。试一试测量自己水杯的容量，

3、算一算每天应该喝大约几杯水。练一练1.怎样使两个瓶子里的水同样多？2.读一读。3.看图填空。4.用自己的水杯测量家中四件不同容器的容量。科学研究表明，为了维持人体的需要，除了侦察过的饮食外，一个人每天应该饮水大约1400毫升。shop.99114.com/50513305shop.99114.com/50662881shop.99114.com/50665133shop.99114.com/50653799shop.99114.com/50659034shop.99114.com/50666877shop.99114.com/50
