School Zone Write & Reuse Books allow your child to practice activities over and over. Each activity can be used to reinforce curriculum objectives or introduce new ones. Use the book in the manner that best suits your child's needs. The Write & Reuse Books are great for summer activities. The activities will help your child retain the skills already learned during the school year or introduce skills that will be taught in the upcoming school year. For best results, we recommend dry erase markers that are made for use by children. (Ages: 7-9)
