 <!-- Provide a quick summary of the dataset. -->
 
-This dataset is introduced by "Evaluating Language Model Math Reasoning via Grounding in Educational Curricula" (link TBD), and includes problems drawn from two open educational resources (OER): Illustrative Mathematics and Fishtank Learning. Problems are labeled with *mathematical standards*, which are K-12 skills and concepts that problems enable students to learn. These standards are defined and organized by Common Core State Standards.
