When it comes to writing out the explanation of how you solved the problem, many of you are doing a great job of listing out the steps that you took, but then stopping there. The explanations of why you took those steps are still unclear. But this is probably the most important part of the response so I want to make sure that we get it right. :)
During class the last week of school before break in December, when we were working on these in class, I showed you a sample of how I would solve a similar problem. I want to post that here.
The main thing that I want you to focus on is that in your explanation, you need to include the specifics of the problem. You need to make sure that you include the important information that you need to know in order to solve the problem. Include the what the problem is asking you to solve for. And most importantly, include how you solved the problem. Walk the reader through every step of the way. Explain all of your computations.
The problem that I solved was: Henry is building a skateboard ramp. He went to the hardware store to buy 1/4 pound of screws and 2/5 pound of nails. What is the total weight of screws and nails?
I Important Information in the Introduction
S Say what you are solving for
A Always explain what you did and why
T Then answer the question in a full sentence
I = Important information in the introduction
S = Say what you are solving for
A = Always explain what you are solving for and why
T = Then answer the question in a full sentence
Below is my full example of how to solve an extended response problem:
As I mentioned in class when going over my example, I can appreciate more greatly how difficult this task is. I did not have to do this when I was your age. That being said, as a teacher, I understand why they are asking you to do this. But I can appreciate that this is not easy to do. We don't normally think about math in this way, and it is even less common for us to write about math in this way. I am a firm believer that practice makes perfect (or as one student put it, practice makes proficient). So we will continue to practice this skill. Keep in mind: I don't expect perfection, but I do expect that you will try your best.
