## The NSDL Math Common Core Collection

The NSDL Math Common Core collection features digital learning resources that address concept and skills components of the Math Common Core State Standards.The collection is organized by grade level and domain, as defined within the Common Core documents. Resources in this collection include lesson plans, simulations, problem sets with explanations, student activities that provide feedback, and other interactives. The collection will continue to grow as new resources are added regularly.

## What Does It Mean to Associate Digital Resources with Standards?

A primary goal of the NSDL Math Common Core Collections project is to explore new processes for associating digital learning objects with educational standards. The release of this pilot collection represents a starting point for making those resource-to-standards relationships. We are careful not to claim that the resources in this collection are "aligned", which may imply a precision that we don't believe can be achieved unless a resource is developed explicitly to address given standards. Instead, NSDL is interested in surfacing information from educators about the utility of existing resources to support their needs for instruction and assessment around the Common Core. As a result, the resources in this pilot collection have been associated with Common Core Standards through a three-tier internal review process. The collection will next be shared with partner communities of teachers and mathematics experts to provide input on the relative utility of the resources for different learning tasks. NSDL will capture these practitioner data and reassociate them with the resource collection, so that teachers will be able to see the original standards mapping for each resource along with educator-generated information about its usefulness.
