二年级下册数学知识点总结
二年级下册数学知识点总结 第一章——除法 1、用乘法口诀做除法,余数一定要比除数小; 2、应用题当中,除数和余数的单位不一样;商的单位是问题的单位,余数的单位和被除数的单位相同; 3、解决生活问题,如提的问题是“至少需要几条船?”,用“进一法(用商加1)”,乘船、坐车、坐板凳等,读懂题目再作答。 第二章——方向与位置(认识方向) 1、地图上的方向,口诀:上北下南,左西右东;辨认方向时要画方向标。 2、“小猫在小狗的( )方”,“( )在小狗的东面”,是以小狗家为中心点,画出方位坐标,确定方向;“小猪在小马的( )方”,“小马的( )方是小猪”,是以小马家为中心点,画出...
