Learning workshops for an interdisciplinary and action-oriented subject education. The subject-oriented workshop series for 3rd and 4th grade builds on the successful Anton & Zora workshop series (1st/2nd grade) while offering a new age-appropriate workshop concept. Three workshop components 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" component, 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 approach the central theme and examine it in an action-oriented, experimental, and playful manner from all angles.
