In Number and Algebra

This series of modules provides a suggested sequence of activities for developing the mental computation of students. The activities are aimed mainly at developing specific strategies for processing mental calculations. The complete series is intended to serve as a practical classroom resource for teaching thinking strategies for mental computation in a coherent and sequential manner.
