The sample items and performance tasks are intended to help teachers, administrators, and policymakers implementing the Common Core State Standards (CCSS) and preparing for next-generation assessments.
The Council of the Great City Schools has designed this Common Core Works website to provide member districts quick access to reliable information, tools, and resources for implementing the Common Core State Standards (CCSS) in English Language Arts/Literacy and Mathematics, and the Next Generation Science Standards.
ASCD (formerly known as the Association for Supervision and Curriculum Development) has created a wealth of resources - professional development, lesson plans and modules, and other materials to successfully implement the CCSS. When you register on the website (for free) and create an account, you can save your searches, organize your tools and add notes.
The Lexile® measure of text is determined using the Lexile Analyzer®, a software program that evaluates the reading demand—or readability—of books, articles and other materials. The Lexile Analyzer measures the complexity of the text by breaking down the entire piece and studying its characteristics, such as sentence length and word frequency, which represent the syntactic and semantic challenges that the text presents to a reader. The outcome is the text complexity, expressed as a Lexile measure, along with information on the word count, mean sentence length and mean log frequency.
