Explaining about how wording can make a difference.

We have talked about how every word problem is a little different. We have to put on our investigating hats and look for all the evidence. What is the problem asking us to solve? Are we using division, multiplication, subtraction, or addition? What would we do if we were in the situation? Then I have the boys write two sentences on why they chose the operation that they did. This helped them to evaluate their answer. Some of the boys were able to see why what they chose was wrong at first. Their answer did not make since and they reevaluated what they needed to do to solve the problem. I felt this was a great activity for the boys because they saw that even if they were wrong at first it was ok and were able to go back and get the right answer before turning in their problem.
