Can not tell them it meant something different because they are on a mission to "fashion" the boat. Where I son made the boats carefully and very realistically but when he got to the part that said "reenact" he clearly interpreted that as blow up in a million pieces after a realistic boat is carefully made. 
I remember he had to make the boats a few times just to reenact the demise. I am finding repeating the guides is fun.
I love remembering what my other kids thought and comparing it to my two very different younger children. It was great the first time around but the second time is even more fun I think. In case you are questioning repeating guides, I am actually finding the repeat to be a blessing. I could easily go for a third time. 
Every time I do a lesson I remember things with my older kids and it's just so fun to see how the younger ones will respond to the same things. I pretty much let my kids interpret the activities themselves and step in only if needed. It's amazing how much and how different what they learn is just by letting them put their own twist on things. My only issue is keeping my kids in CTC out of the Bigger activities because they want to do them again too and direct the little ones.
