Holt Biology Homeschool Lesson Plans

To the Parent: We recommend that you briefly review the topics in each chapter of Holt Biology to get a general understanding of how and when they are introduced. We also suggest that you read and familiarize yourself with the following sections of the Holt Biology Homeschool Package before beginning instruction:

· Hands-On Learning, TE pp. T8-T9: an introduction to features such as Inquiry · · ·

Labs, Quick Labs, Skills Practice Labs, Chapter Labs, and Virtual Investigations Meeting Individual Needs, TE pp. T12-T13: an inventory of inclusion strategies and activities built into each chapter, as well as further suggestions for students who may be experiencing difficulty with the subject matter Reading and Comprehension, TE p. T6: an overview of features used throughout the text to make topics more engaging and accessible Safety Guidelines for Teachers, TE pp. T24-T28: rules, techniques, and tips for a safe, clean, and productive lab area

Other Important Information:

· While pages in the textbook are numbered continuously from chapter to chapter,

page numbers for each chapter in the Chapter Resource Files are not sequential from activity to activity. Page numbers are referenced in the lesson plans to help correctly identify exercises. Chapter correlations for National Science Education Standards are provided for your reference on TE pp. T16-T23. Consider collaborating with other homeschool families for group activities, projects, and labs.
