"You are no longer my friend!", "I don't want to sit next to her!" First graders often have a tough time in the first weeks. Everything is new, and they quickly need to find their way in a new class community. It is important to be able to handle one's own and others' feelings. With this teaching series, you are well-equipped to promote empathy among the children. Together with the little caterpillar, the first graders embark on a journey of discovery and accompany her through nine exciting stories about friendship, disappointment, conflict, or anger. Through the little caterpillar, the children learn to express their feelings, empathize with others, and counteract conflicts. The individual lesson plans offer many opportunities for differentiation and can be tailored to each learning group. With worksheets for each story.
