Recommended to all elementary teachers and ELA/English teachers for middle school and up. While the recommended ages are for use with students 9-13 years, I have used materials and activities starting with 4th graders through 12th grade. As an introduction, for mastery, or review. The activities are engaging and quick-write rules a must have. Used daily as the inspiration in quick-write activities which demonstrated significant, rapid growth in students' writing and during grammar instruction.
