We promise to give teachers a break! Our resources are classroom ready, turnkey, and easy to teach. Lessons come loaded with instructional content, practice activities, worksheets, project ideas, and assessments. Instructional bells and whistles such as classroom slides (free!), vocabulary e-flashcards (free!), and extra practice activities make teaching our programs a breeze. They’re also easy on the budget.
