小学一、二、三年级,我们学练的都是整数加、减、乘、除法及其混合运算。小学四年级又学习了小数和分数,还学到了一种新的算法——列方程解应用题。 本期活动内容,就数的范围来说,从整数扩大到小数和分数,以计算方法而言,在算术方法的基础上,又增加了代数方法。 少年珠心算课外广场活动,有如下两个鲜明特点: 一是注重选题:选趣题、名题、典型题,以一当十,
Primary one, two, third grade, we learn are integer addition, subtraction, multiplication, division and mixed operations. The fourth grade elementary school also studied the decimal and the score, also learned a new algorithm - column equation solution application problem. The content of the current activity, in terms of the range of numbers, expanded from integers to decimals and fractions. In terms of calculation methods, algebraic methods were added to the mathematical methods. Adolescent extra-curricular extra-curricular activities, has the following two distinct characteristics: First, pay attention to the topic: the fun topic, the title, the typical title to one when the ten,
