Focus of the work…
Promote student inquiry into operations - the process opposed to the answers Moving away from rote “tricks” and algorithms to a more conceptual understanding of the math Becoming proficient in using math language and representations to communicate student thinking Visual models: introduced through “strings” and real life context inquiries
