Module 1 Lesson 10 slide presentation with answer keys! Engage NY/Eureka Math is a free downloadable program located at GreatMinds.org. I did not write this program, however, I am selling this supplemental slide show of student problems as a way to help busy teachers teach more fluidly and efficiently to their students. I hope it saves you as much time as it has me! For more helpful items please, please see my Guided Student Journals. Thank you for looking!
