Learning workshops for interdisciplinary and action-oriented subject teaching. The subject-oriented workshop series for grades 3 and 4 builds on the successful Anton & Zora workshop series (grades 1 and 2) while offering a new age-appropriate workshop concept. Three workshop modules enable a holistic open teaching approach that gives children the space to independently discover and explore content according to their interests and needs: With the "Research" module, children have the opportunity to pursue their own interests related to the workshop topic and explore their self-chosen research theme in depth. With 25 interdisciplinary workshop tasks, they independently engage with the central theme, examining it in a hands-on, experimental, and playful manner from all angles. Activities take place in the classroom.
