Bo wants to find the perfect container to show off his traditional marbles for the Cherokee national Holiday. It needs to be just the right size: big enough to fit all the marbles, but not too big to fit in his family's booth at the festival for the Cherokee National Holiday. And it needs to look good! With his grandmother's help, Bo tries many containers until he finds just the right one. A playful exploration of volume and capacity featuring Native characters and a glossary of Cherokee words.
