This book, for teachers of grades 3 to 6, describes teaching strategies and lessons to help students become more proficient in computation. The first two units in the book discuss posing and solving problems and how to do an investigation from beginning to final write up and presentation.
The other four units are centered around addition, subtraction, multiplication, and division. The lessons consist of investigations that provide a context for learning and the purposeful application of skills. Several examples of children posing and solving problems and investigating mathematical topics are included throughout the book.
The unit on addition starts with a discussion between the students and teacher about the concept of strategy. The teacher then has the students look for patterns formed by repeatedly adding nine. By the end of the unit the children are investigating patterns found in Pascal's Triangle.
