What is the relationship between EngageNY and Eureka Math?

The New York State Education Department contracted with our organization in 2012 to create a mathematics curriculum called EngageNY, now known as Eureka Math. The curriculum is available on both the EngageNY and Great Minds sites for free download. Between the two sites, the curriculum has been downloaded more than 13 million times by users in all 50 states.
