Teaching content: People’s Education Edition “compulsory education curriculum standard experimental materials” fourth grade volume “tree planting problem”, 117 cases 1 and do one. Teaching material analysis: The fourth part of the second volume of the eighth unit of “mathematical wide-angle” is mainly infiltrating the thinking of some of the tree planting problems, through some practical real life problems, allowing students to find some of the laws, extracted from the mathematical model , And then use the found rules to solve some simple practical problems in life. The solution to the problem of tree planting is a kind of mathematical thinking that is widely used in real life
