Beaver is clever, sensitive, and confident in his calculations. His quick thinking helps him spot solutions right away, but when he takes over a group science project, Bunny, Hippo, and Alligator feel frustrated and left out. Beaver knows his pulley system works. What he does not understand is why finishing the project is not the same as working together. With guidance from Teaching Assistant Tapir, every member of the group recognizes a skill they are still practicing. Beaver is learning to slow down and listen. Bunny and Hippo are learning to speak up and share their ideas. Alligator is learning to think more positively when others contribute. All members recognize that working in a group is difficult. When the animals try again, they discover that listening, communicating, and combining their strengths makes both their project and their team stronger. Beaver's Group Time Grumble is a neurodivergent-affirming picture book about flexible thinking, teamwork, communication, perspective-taking, and belonging. Ideal for reading at home or using in classrooms, libraries, counseling, social skills groups, and social-emotional learning lessons with children ages 4 to 12 years old. - Social-emotional learning (SEL) - Classroom community building - Autism acceptance and neurodiversity conversations - Friendship lessons - School counseling - Family discussions about kindness and belonging
