Worried about using Heggerty and Fundations

So i am leaving my teacher job that I hated to get a job in a new district and I am super nervous about it. I have always taught high school and now I am teaching kindergarten. I have to teach lessons from two curriculums- Heggerty and Fundations- and I have never used either before. I know the lessons are in the manuals but what it does not tell me is if I have to create packets for the kids and/or create displays online for them. Would it be okay of I sit in front of my kids with the notes right there or do I have to memorize everything. Any guidance would be appreciated?
