Teamwork Isn't My Thing, and I Don't Like to Share! by Julia Cook

His teacher wants him to work with bossy Bernice, messy Frankie, and Norma (who just sits and picks her nose) on a report about Egyptian mummies. After a frustrating school day with his “team,” RJ goes home to find only one cookie left in the jar - and his mom makes him share it with his sister! With the help of his coach, RJ learns that working as a team and sharing are skills needed not just on the soccer field, but in school and at home too!
