Extra Practice for Primary Mathematics is a series of six supplementary books that will prove invaluable to students in their understanding of mathematical concepts. This series follow the topical arrangement in the Primary Mathematics U.S. Edition series. The exercises generally provide problems of a similar style and level of difficulty as the course material covered in the Primary Mathematics U.S. Edition series. The exercises are short and specific, so instructors may assign only those topics in which the students needs more practice. This, together with the simple language used, will allow students to review mathematics with minimal guidance. The practice material aims to consolidate and reinforce the mathematical skills taught in the Primary Mathematics series. Answers are in the back of each book. Grade 6
