This book provides opportunities for older and younger children in different grades to work together on standards-based activities. It contains over 40 lessons in which elementary school students of different ages can learn together. Each activity can be assigned as a special project or as part of an organized program in which teachers work together on a regular basis. For each activity, you will be provided with:

- standards -- reading, writing, or mathematics

- assessment rubrics

- student handouts, ready for photocopying

- to help you assess your students objectively and confidently, about a quarter of the lessons are accompanied by samples of student work along with its score and an explanation of why the work deserved that score.
