Amplify Vocabulary is a digital supplemental program designed to help all students in grades 4–8 master essential academic and Tier II vocabulary. Through a series of fun, digital activities, students encounter words on multiple occasions and must show a clear understanding of a word and its usage in order to demonstrate mastery. Differentiated streams for below- and above-grade-level readers are included and adapt based on student performance. Students can begin in the below-grade-level stream but be sent more challenging words as they progress in their vocabulary work. Since these streams are not visible to students, they can focus solely on learning the words they need.
