This is a powerpoint presentation of the Engage NY materials following Lesson 26 for 6th grade math. It is meant to guide a teacher and the students through the examples outlined in the curriculum. I used this lesson in a "Price is Right" format adding additional problems for students to work cooperatively to solve prior to the lesson problems that are posted in this powerpoint. I removed the logos as they are copyrighted. Feel free to add them for your classroom use to enhance the presentation.
