This is a direct instructional lesson. I hope this eighth lesson (6-8) in my Unit 6 on Functions works well for you and your students and saves you valuable personal time. This lesson reviews differences between Additive and Multiplicative Relationships while focuses on Slope and Y-intercept of linear functions. VA SOL 7.10 is supported by this lesson. If you liked this lesson, please look for all the other lessons and activities for this Unit in my TPT store. I plan to put the whole unit in a bundle as soon as I upload all the lessons. I also have other Units for Virginia Math 7 in my TpT store. This lesson is intended for single use in your classroom. Please direct your colleagues to my store if they would like to use my products.
