This article presents a systematic approach to teaching Computer Modeling in 4th grade, aimed at developing digital competencies and fostering both algorithmic and creative thinking. The approach is designed for students learning programming through the Scratch environment, a subject taught from 3rd to 7th grade in Bulgaria.

The focus is on a project-based learning model where students not only acquire programming skills but also develop a genuine interest in computer science. Through various projects, students are introduced to algorithmic concepts, such as binary search, and strengthen their logical thinking in a playful and engaging way. Additionally, the approach encourages creative thinking by allowing students to create their own characters, moving from modifying existing sprites to designing entirely new ones. The tools for working with vector graphics in Scratch enhance this creative process.

This article will describe the methodology behind the system and provide concrete examples from the curriculum to highlight how this approach helps students develop both computational and creative skills, with an emphasis on its practical application in the classroom.

The article will provide specific examples from the curriculum, demonstrating how the system is applied in practice. Additionally, it will discuss the implementation of the approach with future teachers, offering an analysis of student feedback regarding the new subject. This feedback indicates the positive impact of the approach on both the technical and creative skills of students, highlighting its potential for broader application in teacher education programs.
