Achieve the Core is a new website launched by Student Achievement Partners, an organization founded by authors of the Common Core State Standards, to share free, open-source resources to support Common Core implementation at the classroom, district, and state level.
Teaching Channel Common Core Videos - this website includes a growing collection of videos that focus on the Common Core State Standards, some of which focus on the background of the Common Core in certain grades/subjects, while others highlight instructional practices aligned to specific standards.
Illustrative Mathematics Project - this website offers guidance to states, assessment consortia, testing companies, and curriculum developers by illustrating the range and types of mathematical work that students will experience in a faithful implementation of the Common Core State Standards. The website features a clickable version of the Common Core in mathematics and the first round of "illustrations" of specific standards with associated classroom tasks and solutions.
Learning Express Library (Test Prep) - Whatever your goal, LearningExpress Library's resources will help you succeed. Each of our Learning Centers offers the practice tests, exercises, skill-building courses, eBooks, and information you need to achieve the results you want—at school, at work, or in life.
