Dot patterns are open share “number talks” that provide educators and their students with opportunities to describe and make sense of the structure of number. Within the context of describing how many dots one sees, a student can provide more insight by sharing the ways the dots are being chunked or grouped visually. This can naturally lead to conversations about the numeric expression for the dot pattern, use of different properties (commutative, associative, distributive), and ideas about the equivalence.
