The GO! Welcome SLIFE™ and Welcome SLIFE™ libraries were created for English learner tweens and teens who may be migrant students, refugees, or students who for other reasons have had limited or interrupted formal education. While the reasons for their limited or interrupted learning may differ, their educational needs are similar. The emergent-level Hi-Lo Books™ in the GO! Welcome SLIFE™ and Welcome SLIFE™ libraries were developed around five genres with twenty key topics that will enrich a SLIFE student’s journey. Each book pair features a nonfiction book addressing a key topic along with a fictional story that features a real-life application of that topic. A comprehensive instructional support guide and vocabulary card set are also included for deeper learning. Special focus is given to 200 content-related vocabulary words to support vocabulary acquisition for striving readers.
