Onions Have Layers Lesson Plan

Welcome to learning fun with the National Onion Association Onions Have Layers Lesson Plan. This series of cross-curricular lesson plans for Grades 1-6 were developed and reviewed by teachers. Each lesson plan on food and nutrition includes correlating materials such as PowerPoint presentations, student activities and worksheets.

All lessons align with national core standards in science, math, reading and writing for grades 4-6, yet are easy to adapt for upper grades and consumer outreach.

The National Onion Association is excited to provide a resource for your classroom or your home school with layers of information and fun hands-on activities to engage your students and enhance their education along with the help of the humble onion.

We took great care writing each lesson plan on food and nutrition and we hope you will find the information fun and factual and the lessons easy to implement in the classroom. We welcome you to contact us with your comments and feedback.
