This workbook offers students additional practice as they explore the five themes from the new IB Diploma Language ab initio guide (first examination 2020): identities, experiences, human ingenuity, social organization, and sharing the planet. It helps students further develop their Spanish skills with additional exercises that complement the activities of the student book, focusing on grammar and vocabulary. The workbook is ideal for teachers who need differentiated exercises for their class and can be used for independent study and review.
