We have used Eureka Math at our school for 4 years now and it is overwhelming, especially in the beginning! Some of the strategies that they want the kids to use, especially ones involving multiple steps, are difficult a for the students, especially struggling students. It does get a little easier the second year you teach it because you start to remember specific strategies and lessons that were difficult and you can modify or spend additional time on skills as needed.

One resource that I found out about last year is

www.zearn.org This is a free website that matches the Eureka curriculum almost exactly. It is broken down my modules (they call them missions) and then individual lessons. Each lesson will show a video and have guided practice to help teach the skills. We usually do this together in whole group each day at the beginning of our math block, but you can also set up student accounts and have the kids work through it at their own pace. If you haven't used Zearn definitely check it out. It has truly been a life saver for me!!

Hang in there! Feel free to PM me if you have any specific questions.
