苏教版五年级第一单元“方程”的教学目标主要是:理解方程的含义,初步体会等式与方程的关系,初步理解等式的性质,会用等式的性质解简单的方程,会列方程解决一步计算的实际问题。教材所涉及到的方程主要包括两类:一类是x±a=b,解方程的依据是等式两边同时加上或减去同一个数,所得结果仍然是等式;另一类是x×a=b,解方程的依据是等式两边同时乘或除以同一个不等于0的数,所得结果仍然是个等式。
The main objective of the first unit of the fifth grade of the Sujiao edition “equation ” is mainly to understand the meaning of the equation, to understand the relationship between the equation and the equation, to understand the nature of the equation and to solve the simple equation using the nature of the equation , Will list the equation to solve one-step calculation of the actual problem. The equations involved in the textbook mainly include two types: one is x ± a = b, the solution equation is based on both sides of the equation plus or minus the same number, the result is still the equation; the other is x × a = b, solving the equation is based on the fact that both sides of the equation are multiplied together or divided by the same number not equal to 0, and the result is still an equation.
