小升初数学专项-口算题
小升初数学专项-口算题近在咫尺了,考生们是否已经准备好考试了呢?考试前的复习是很重要的哦,下面是小考网为大家准备的考试实用的复习练习题,希望能够帮助大家高效复习,这里先预祝考生们考试顺利。
口算发源于“日常数学”后,它融合了数学的特征与数学教育的规律。
口算的最一般基础是数意义上的“凑整”。
在此基础上,其加、减运算建立在结合率基础上,乘、除运算建立在分配率及分解因数基础上口算对非常重要。
越来越的学校重视奥数成绩,而奥数的成绩离不开基本技能的训练,如果抛开基本训练的教学,如同走马观花,蜻蜓点水。
所以如果学好了“口算”那么同学们做作业不再用草稿纸,口算直接写答案!当然得提前练好基本功才可以。
要引导学生在理解的基础上掌握基本的口算方法,坚持经常练习,逐步达到熟练。
1、会算法——笔算训练,现今我国的教育体制是应试教育,检验学生的标准是考试成绩单,那么学生的主要任务就是应试,答题,答题要用笔写,笔算训练是教学的主线。
与小学数学计算方法一致,不运用任何实物计算,无论横式,竖式,连加连减都可运用自如,用笔做计算是启动智慧快车的一把金钥匙。
2、明算理—算理拼玩。
不但要使孩子会算法,还要让孩子明白算理。
使孩子在拼玩中理解计算的算理,突破数的计算。
孩子是在理解的基础上完成的计算。
3、练速度——速度训练,会用笔算题还远远不够,小学的口算要有时间限定,是否达标要用时间说话,也就是会算题还不够,主要还是要提速。
4、启智慧——智力体操,不单纯地学习计算,着重培养孩子的数学思维能力,全面激发左右脑潜能,开发全脑。
经过快心算的训练,学前孩子可以深刻的理解数学的本质(包含),数的意义(基数,序数,和包含),数的运算机理(同数位的数的加减,)数学逻辑运算的方式,使孩子掌握处理复杂信息分解方法,发散思维,逆向思维得到了发展。
孩子得到一个反应敏锐的大脑。
