Reading, Writing, and Math Lessons

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, and 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.
