The 165 lessons include instructions for teaching with manipulatives to develop math understanding and problem solving skills. Each lesson includes Practice and Review activities with a spiraling review and colorful Student Worktext pages with answer overprint. Each chapter concludes with Chapter Review and Cumulative Review lessons. A Chapter Overview preceding each chapter contains a theme story about Matt, the construction worker, and Paddy, the beaver, a chart with materials to be gathered and prepared and lesson objectives, and a bulletin board illustration and description. A Little Extra Help section provides ideas for helping the student who is experiencing difficulty with the concepts. The Teacher's Visual Packet is also included for use by home educators and those teaching small groups. Colored transparencies may be made for use in the classroom. The answer key for the Math 2 Reviews is located only on this CD.
