The mention of Walmart usually elicits one of two reactions, either admiration for unbridled capitalism or contempt for exploitative business practices. Either way, Walmart's time at the top might be in jeopardy because of a small, but growing, retail chain that has managed to match Walmart's prices without employing the same ruthless tactics. Your students will enjoy discussing competition in the retail industry and business strategy in this highly engaging lesson!
This lesson is appropriate for adult English language learners at the advanced level, but is adaptable for upper-intermediate learners. It has a discussion phase, vocabulary study phase, a reading/listening passage followed by reading/listening comprehension questions, and finally some additional conversation and role-play activities. I have used it in individual and large group settings, and found it to be a very flexible and useful resource.
