As they act out each part of the story, students use number and operation symbols to record what has happened to Alexander's money. The student uses logical reasoning to make sense of his or her world. Clarifying Activity Students work in small groups. Each group receives a hundreds chart with the first few numbers in a pattern colored in. The student uses logical reasoning to make sense of his or her world.
Students observe the pattern and try to describe the pattern.
