Lessons are divided into three types of activities that are all found in the student book. The Investigations activities explore data to discover and explain a mathematical rule or concept. Extension activities continue the data investigation. The Assessments section contains four questions where the student applies newly learned rules and concepts to solve problems and explains the problem solving procedure. A sample Extension activity calls for a class survey to determine if more people were born on odd or even numbered days.
Students also make a graph with the data and write a sentence describing the graph.
The student book contains all lesson activities, two vocabulary activities, and three review lessons. The teacher guide includes lesson objectives and teacher notes, along with sample solutions and reproducible masters. ENC does NOT distribute this resource.
