As we worked to develop this resource for teachers of 10th grade ELA, we constantly asked ourselves how to balance providing a helpful guided structure that saves planning time, with allowing enough flexibility that teachers can make strategic choices to suit their interests and needs. Based on extensive customer feedback and with input from our Content Advisory Board, in this edition we’ve provided an even clearer structure and more guidance on how to create units, while still preserving a good deal of flexibility. This edition features dozens of new and engaging texts, including nonfiction by DeRay McKesson, Dolores Huerta, Yuval Noah Harari, Steven Hawking, and Toni Morrison, and literature by Lesley Nneka Arimah, Oliver De La Paz, Richard Blanco, Ha Jin, Li-Young Lee, N. K. Jemisin, Joy Harjo, and Nana Kwame Adjei-Brenyah.
