Curriculum materials for ELA subjects are structured into 4 levels of hierarchy. You can navigate by grade, then by various modules within the grade. Each module is divided into units, and each unit is further divided into lessons.
The Common Core State Standards are important because they will help all children – no matter who they are – learn the same skills. They create clear expectations for what your child should know and be able to do in key areas: reading, writing, speaking and listening, language and mathematics. If you know what these expectations are, then you can work with the teacher and help your child prepare.
