HMH’s English 3D® is a comprehensive, K–12 English Language Development (ELD) curriculum created by Dr. Kate Kinsella, designed to help multilingual learners—from newcomers to long-term English-learners—rapidly develop academic English proficiency across reading, writing, speaking, and listening. 

With an asset-based approach, the program leverages students’ linguistic and cultural strengths through translanguaging and home-language connections, while consistently applying explicit instructional routines that align with state proficiency assessments, academic standards, and Common Core goals. Backed by research showing significant reading and writing gains, English 3D equips both students and educators with the tools needed for language growth and academic success  .
