Educator, academic, and reader
From an educator's perspective, The Very Hungry Caterpillar, is my favorite Eric Carle book. Early elementary children find this book engaging and enthusiastically perform choral reading. The content lends itself to thematic learning and can be utilized across the curriculum: ELA, science and health, mathematics, art, and social studies.
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.
