If students develop a good habit of examining questions, their ability to solve problems will be obviously improved.
Second, guide students to use various strategies flexibly and advocate diversification of algorithms.
Make students familiar with various strategies to solve problems, and be able to use different strategies flexibly according to the characteristics of problems. In the usual process of mathematics teaching, students should be encouraged to get rid of fixed thinking, think from different angles, solve problems with different methods, vigorously advocate the diversification of algorithms, and advocate the optimization of strategies on the basis of diversification.
Three. Through discussion and communication, find out the most suitable strategy from various methods, and really improve students' ability to solve practical problems.
Fourthly, mathematics teaching should establish the idea of "student-oriented development", closely combine mathematics learning with real life, improve students' interest in learning mathematics, let students find and explore problems in familiar and interesting life situations, cultivate students' mathematical ability, and cultivate students to look at life from a mathematical perspective and solve practical problems in life. Let students learn mathematics in life and feel life in mathematics.
