In a math-rich early childhood classroom, children will have many opportunities to work with math stories and operations. This includes having children’s picture books that explore these different math stories. Before we ever introduce symbols to pull the mathematics out of the context, children need many experiences seeing that three friends and three more friends is six friends, or that three pencils and 3 markers make 6 things for writing. Picture books can be a great starting point for these explorations.
