Developing informatics thinking, focusing on an algorithmic approach to problem solving is an integral part of informatics instruction at both elementary schools and high schools. The complexity and diversity of informatics instruction can be ensured not only by diverse tasks, but also diverse approaches to the task and diverse results. The diversity of tasks depends on the context into which a task is placed. The student needs not only to understand the context, but also be able to create a problem solving process in the required form, i.e. write an algorithm.Intended for elementary and high school students, the informatics competition ?Beaver of Informatics? is held in a number of countries all around the world. During the course of the competition, students solve various informatics problems, many of which are aimed at informatics thinking. Following the analysis of the competition tasks, task categories were defined with regard to the way of writing the solution, i.e. the way of writing the algorithm. The paper introduces the results of the analysis of the ?Beaver of Informatics? tasks intended for elementary school students, which were aimed at forms of writing simple algorithms.
