Welcome to Longman Cornerstone! We wrote Longman Cornerstone to help you succeed in all your school studies. This program will help you learn the English language you need to study language arts, social studies, math, and science. You will learn how to speak to family members, classmates, and teachers in English. Cornerstone includes a mix of many subjects. Each unit has four different readings that include some fiction (made-up) and nonfiction (true) articles, stories, songs, and poems. The reading will give you some of the tools you need to do well in all your subjects in school.
