Llama Llama Time to Share - Anna Dewdney

This is such a great book for new Kindergartners who may not have much experience with sharing their stuff with other children.  Llama, llama, Time to Share shows that when you do share your things, you can end up making new friends and having them to play with.  This could be used up to first grade.  I would use it if a situation came up where my class or a couple individuals were having trouble sharing or I might read it on one of the first days of class.
