The Teacher's book includes notes for every unit, and provides numerous ways to extend the material. Unit overviews give a map of all the resources available, and include ideas for songs and useful web links. Included in the CD-ROM pack are printable worksheets to revise and expand core vocabulary and grammar, additional unit reviews for extra vocabulary support, and communicative worksheets for pair-work speaking. These resources are perfect for mixed ability classes, offering support for weaker students and extension material for faster learners.
