The National PTA and the Council of Great City Schools (Common Core Works) offer free, downloadable brochures with CCSS information organized by grade level. Each brochure or roadmap is in color and available in English and Spanish. The publications give some background about the Common Core, offer specific examples of skills and expectations for that grade level, and suggest ways parents can help their children succeed.
