Information about the series: Children are constantly experimenting to understand the world around them. The Research Stars tap into this childlike curiosity and support foundational education in this area. With the Research Stars, they can expand and reinforce their skills in subject lessons. Children can independently conduct simple experiments and solve tasks related to comprehension reading, logical thinking, as well as the development and review of content. The workbooks convey relevant subject matter in a playful way and can be used independently of any teaching materials, both in the classroom and at home. The integrated answer booklet allows for self-assessment. Children receive star stickers for successfully answering the tasks.
