Primary Colours is an activity-packed, six-level course for young learners aged six to twelve years. Pupil's Book 4 uses language to help young learners achieve goals in the classroom, motivating them with activities and projects and maintaining their enthusiasm with tangible evidence of their accomplishments. Learners integrate the skills that they have learned through cross-curricular 'Know it all' sections, focussing on areas such as geography, history and science.
