Each page in this book provides problems at Levels 1 and 2 along with an investigation. At Level 1, students are generally solving one-step problems in which they need to use one mathematical operation and the language indicates the required operation. The Level 2 problems involve more sophisticated language and may involve more than one operation in order to calculate the answer. The investigations draw students in to address real-life situations. To successfully solve the investigations, they must think and work mathematically, as well as use their knowledge of a range of mental and written strategies and demonstrate their overall competence in mathematics.
