Abrir Paso set 2 A-M - These texts serve as enrichment material and are used alongside a middle or high school textbook to give students the opportunity to deal specifically with cultural material. The texts serve two further purposes: reading and vocabulary development. The emphasis of this set is on México, Central America and the Caribbean countries. Thus, find out how the coquí, Puerto Rico’s famous mascot hatches; how Mexico City has tried to reduce pollution; how the monarch butterfly has survived despite their forests being in danger, and much more. Content-based units catch the imagination of many different students for they are varied, interesting and diverse.
