Predict: I predict I will need to use division and addition in this problem.
Clarify: I have no words, sentences or phrases to clarify.
Find the big question: What are the page numbers?
- I need to start by splitting 333 in half, because they need to be consecutive. Picture a book, the page numbers are consecutive,, aren’t they?
- It is 166.5 but I will round that up to 167.
- So I will round down to 166.
The mathematicians toolbox strategy I used in this problem was break it into manageable parts.
