Extra Practice reinforces and consolidates the skills learned in the Primary Mathematics series. It is for both home and classroom use. It allows teachers to identify and assign specific topics that are challenging to students, and exercises can serve as reviews for tests. Exercises generally provide problems of a similar style and level of difficulty as the course material. Answers are included in the back of the book.
