This is a great way to help your students become familiar with their 4th grade Science textbook. The Houghton Mifflin Fusion series is a great resource, but can be a little intimidating to students at first. This will help them understand how each unit is put together. It also covers table of contents, the interactive glossary, and the index. It is written in a way that your higher kids can read and follow along independently, or you can lead your students to find the answers together. Answer key included as well. Please check out my other materials to support your Fusion curriculum!
