# The system of thematic integration

The core of integration of the “Rainbow” textbook teaching material is the topics of the world cognition (the introduction to the natural and the social environment) indicated in the Primary Education curriculum.

The thematic integration system consists of two aspects. The main unit of integration becomes the topic of the week, while other subjects are organised around it. For example, in grade 1, the topic of the first week of January is “The clocks tick day and night”. The illustration shows how each subject is integrated into the topic of the week.

The weekly topics are linked to a more general monthly topic, for example:

Grade 1, **January – ****“****Wheel of Time****”
**Week 1 – “Clocks tick day and night”

Week 2 – “Time flies”

Week 3 – “What’s the story?”

Due to school holidays and the teachers’ reserve time, most of the monthly topics have three and not four topics. Therefore, over the course of four years, about 130 topics are covered.

The uniqueness of the “Rainbow” textbook lies in the system of thematic integration, which covers all the topics of the world cognition curruculum. It is both horizontal – all topics are set in one school year, and vertical – the same or a similar topic can be discussed in more and more detail each year moving towards a higher level. For example, a more elaborate discussion of the human body, more historical facts, or a more specific discussion of the natural processes. The coherence of the horizontal unit laid out in one year, is based on a consistent and methodological presentation of knowledge in languages, mathematics, and other disciplines.
