This site focuses on building reading skills. Children practice basic reading skills through online games and activities. Children, with adult assistance, sign up for free or teachers can sign up. In the QA section it states: 'Teachers can add as many students as they want to their accounts. They can even organize their students into “classes” to help keep things organized."
