Kindergarten has had so much fun doing projects based on Bill Martin, Jr. and John Archambault's picture book, Chicka Chicka Boom Boom! Today, as a STEM activity, they had to design their own coconut trees using classroom items, like stacked dice for the trunk, Popsicle sticks for the branches, and Alphabet letters! Kindergartners experimented with their tree designs and counted the amount of letters their trees could hold.
