This is a free 2 lesson sample from the entire unit 1 materials currently for sale on my site. This is the Engage NY/Eureka math curriculum materials, which I have reformatted over the last couple of years to make them more "student friendly" and usable in my classroom.
The student notes are formatted to be printed double-sided, leaving a margin wide enough to be 3-hole punched and placed in a folder without text being affected. The Independent Practice (Problem Sets) have been formatted to leave enough room for students to show work, and can be printed double-sided when there is more than one page of practice. The exit tickets are designed to be printed one-sided, and are printed two-to-a-page when appropriate.
