Predict: I predict that I will need to use division adn addition in this problem.
Clarify: I have no words, sentences or phrases to clarify.
Find the big question: What are the two numbers?
- The first thing I did was divide 97 by 2= 48.5
- but they are consecutive whole numbers.
- So I rounded up to 49. But 49+50=99, not 97.
- So I rounded down to 48. 48+49=97!
The answer is 97.
Summary: The mathematicians toolbox strategy I used is this problem was work backwards.
