Today PJ and I worked on a solving two step equation scavenger hunt. The answer to one problem lead us to the next question, kind of like a maze. PJ did an excellent job with it. He is able to do multiple steps in his head, which is quite impressive. I complimented him but then reminded him of the importance of showing his work. I said to him, "what if the answer is 28 and you accidently wrote 82 with no work. I would not know how you got to that solution. However, if you write down the steps, I can see your thought process and also where/how you made the error. That means you could get partial credit. But if you just wrote the answer and it's wrong you get no credit." That motivated him a bit more to show his work. We also discussed how we can check our answers. By substituting our answer back into the original problem and seeing if it makes sense.
