The topic of Polygon Area in Unit 6 of Grade 5 Mathematics is the key and difficult content of this semester, which often appears in problem-solving and manipulation problems, and is also a type of question that many students are prone to make mistakes. For simple polygons, the area can be solved by formulas. However, many students don't know how to do the slightly more complicated questions. In fact, the method is also very simple, students can simplify the complex figure by making auxiliary lines, and then solve the area of these figures separately and add them to find the area of the complex figure. This type of question also often appears in the test papers of the elementary school promotion and placement exams, so students must think more in the process of doing the questions, and make the difficult questions simple by drawing pictures and making auxiliary lines.
In view of this, today the teacher has sorted out a set of special training for the students in the sixth unit of the fifth grade mathematics "Polygon Area", the question type is comprehensive and comprehensive, which is very suitable for students to carry out targeted consolidation training after the completion of the Xi, which can help students find the places they do not understand in time, which is very helpful for improving scores. Parents and friends can print a set for their children, and ask their children to practice according to their children's learning Xi to consolidate what they have learned.
