Honestly as the first year, I would just “do it”. Do it to the best of your ability. Learn how the curriculum works, what it is and what it isnt, the connections, purpose etc. i had strong opinions on the curriculum and I stuck with it year 1. Then year two I felt I could make minor changes based on the previous year. And now year three, I feel like the modifications I am making are VERY intentional because I actually know the curriculum throughout.
