OPD Workplace Reading Library Audio CD features recorded versions of A Big Night at Maria's Café, An Important Guest at the Shelton Hotel and Math and Max, all based on topics in OPD with narratives focusing on the workplace. Each of these three titles provides the contextualized reading practice students need to learn and retain new vocabulary. Other activities reinforce vocabulary, ensure comprehension and build critical thinking skills. OPD links provide a visual glossary for easy reference.
