The ESL Lesson Library is a new resource on Road to Grammar.
It features 10 mini-units for ESL learners at B1-B2 level.
Each lesson features vocabulary, listening, grammar and conversational scenarios. It should take a learner 15-20 minutes to complete.
Each of the ten lessons is free and works on any phone or laptop. Teachers might consider using them with their smartboard or assigning them for homework.
