This lesson has everything you need to teach a "Thin Slicing" lesson on writing and solving systems of equations from real-life word problems and mathematical scenarios (8.EE.8c). This lesson uses Building Thinking Classrooms strategies for teaching math created by Peter Liljedahl. If you have been looking to implement the Building Thinking Classrooms model of instruction, but don't know where to start, this is a great resource for you.

This lesson includes the following materials:

• Description of how I run a "Thin Slicing" lesson using Vertical Non-Permanent Surfaces (VNPS) in my own classroom.
• 11 Full-Size Task Cards on writing and solving systems of equations real-life scenarios
• Answers for all Task Cards
• "Notes To My Future Forgetful Self" Student Notes Template
• Student Notes answer key
• "Check Your Understanding" student Exit Ticket
• Exit Ticket answer key

This lesson will help your students learn how to write systems of equations from a word problem, encourages rich math discussion, and provides an additional challenge for your students who move at an accelerated pace. This lesson starts with a very low floor to encourage access for all students, and provides a high ceiling with extension questions. Once complete, students can use the provided notes template to record their thinking, as well as a "Check Your Understanding" exit ticket to give you and your students formative assessment feedback on how they are understanding the topic.

This lesson is the 3rd in a 3-part series for 8th grade systems of equations. The two other lessons are:

1. Solving Systems By Substitution Thin Slicing Lesson - 8th Grade Math 8.EE.8b

2. Solving Systems By Elimination Thin Slicing Lesson - 8th Grade Math 8.EE.8b

Please consider using the whole 3 lesson unit when teaching solving systems of equations algebraically for 8th grade. If you want all three lessons, you can buy them in the bundle at a 15% discount, and get a FREE Solving Systems Level Ups review activity included.
