"Way Ahead" is a six-level course for primary school children who are learning English as a second language. At the upper levels, the texts are topic-based, and introduce children to the study skills they need to pursue their studies to a higher level. At the lower levels, the books introduce a cast of entertaining characters who contextualize the language and make learning fun. The structures and functions of the English language are taught through a variety of child-centred activities, which have been carefully graded and are suitable for classes in a variety of cultural backgrounds.
