“一元一次不等式(组)”一章内容的学习是前面“一元一次方程”“二元一次方程组”运算的延续,其中用数轴表示解集又是“数形结合”数学思想的雏形,对于较为复杂的不等式问题的解决又是“化归”数学思想的体现.学生除了掌握基本运算技能外,还得学会对综合问题的剖析,进而上升到对一类问题解决策略的形成.由会一道题,发展成会一组题,进而会一类题, “Unary inequality (group) ” chapter of the learning is the front “a unitary equation ” “Binary equation system ” continuation of the operation, in which the axis with the solution set is “Mathematical thinking of the prototype, the solution to the more complex inequality is the ” Students go back to "mathematical thinking of students in addition to master the basic computing skills, but also have to learn the analysis of comprehensive problems, and then rose to one The formation of a class of problem-solving strategies.From a question, developed into a group of questions, and then a class of questions,
