The content of key tasks on the "area of triangles" in geometry grade 8, the technology of their manufacture and use

Abstract

The continuous growth of the content of educational materials in all subjects of the school, the emergence of new subjects, the development, assimilation, memorization, the effective use of a large amount of information, facts - leads to the improvement of students, overwork and a decrease in efficiency. As a result of excessive pedagogical loads, the quality of teaching remains low.

In this article, we would like to show that it is possible to use key tasks in a problem where students worked only on key tasks during the passage of a particular topic.

In the article, the definition of a key problem was given, and we focused on the requirements for choosing a key problem for certain topics of the subject of geometry.

In accordance with the requirements for the key task, it was proposed to choose a task on a particular topic.

In the article in paragraph 39 of the chapter "Areas of figures" in geometry of the 8th grade  "The areas of triangles" are considered, actual problems related to this topic are selected and a method for solving them is developed. It also shows the use of solving problems other than key problems.

In general, the article ends with the conclusion that if we choose with students a system of problems related to a particular topic and if we teach them to use problem methods to solve other problems, the quality of knowledge will be much better.
