How to describe the problem
The task is an object of mental activity, containing the requirements of some practical transformation or answer to a theoretical question by means of a search. Therefore, first of all you must find in the task a condition that allows you to uncover the relationships (relations) between known and unknown elements of it.
Then consider the structure of the problem. It is divided into condition, justification, decision and conclusion. In the condition of the task, the subject area (objects) and the relations between them are usually indicated. This is basic when describing. Next, you need to justify the theory that is used in the task. And in conclusion you must specify the unknown components, that is, show what you need to find, verify or prove.
You must determine the type of task. It can be connected with algebra, physics, geometry, economics, etc. In the school course, they mainly study the plot tasks. If you need to describe this, you must understand that a task of this type describes a certain plot. In the study of mathematics, plot problems are the most common. Highlight the typology of the plot: tasks for movement, for purchases, for work, for harvest, etc. They are described as well as ordinary ones, but objects of a different kind are used instead of figures.
After the work done, you will only have to combine all the material. And the last thing to do is to clearly formulate the question by the condition of the task, on which the basic answer is required so that the student, when searching for it, does not have any difficulties in solving.
