Third Grade Mathematicians


We just completed unit 2 and the third graders worked on an artifact to put in their portfolios to demonstrate their learning of a math concept in unit 2.
Third graders, please write me a comment and answer the following questions:


  1. What is your portfolio item?  Describe it in detail.  
  2. What math did you have to do?  How does this show that you know how to add and subtract whole numbers?
  3. What do you think of your work?  Would you do anything different next time?



Do your best with your work.  Be a good mathematician and explain all of your thinking.

  1. Here is an example of a really good response:

    The portfolio product that I completed for unit 2 was Frames and Arrows. I figured out the frames and arrows by first looking at the rule which was + 100. Then I filled all the answers to the right first by adding 100 to each number. Then I subtracted 100 to fill in the answers that went to the left. This was really good practice on adding and subtracting large numbers. I think my work is good. I sometimes have a hard time finding the rule when it is missing from a frames and arrows problem.

  3. My portfolio product that I did was How Many Miles? I figured out that the anwser was 858 miles from Seattle to Salt Lake City.
    The math that I leared was counting miles.
    Yes, I am happy with the final product. What I did well was adding up the two numbers to get the anwser.

  4. My portfolio product is In Out boxes.I learned that you can put a math problem in your head with in out boxes by taking the in number and taking the rule number and put it right next to it and then you will have the answer which is the out number. Yes, I am happy with my final product, I did the strategy of using what I already know. I will use a different strategy and maybe I will do it better.

  5. My portfolio product is How Many Miles.Iwrote down how many miles it takes to get from Settel to boise to Salt Lake City. I learned more about distances. Yes, I am happy with my final product because it was a very fun activity and I did really good adding and I don't think I need to do any better next time.

  7. my portfolio product is a Addition and Subtraction
    puzzles. I learned adding and subtracting and getting better at puzzles and I also got better at adding and subtracting too. I'm happy with my product and I think I did well at making up my own one. I think what I will do differently is think about the problems better.

  14. My portfolio product is my choice and it is a number challenge.What you do is you add sideways and subtract down and in the end you end up with
    numbers at the side and at the bottom.The math I
    learned was adding and subtracting and yes it dose show that I can add and subtract whole numbers.I am very happy with the final product.

  21. My portfolio product is Addition and subtraction puzzles.It is very tricky.There are numbers that have to equal something and there were two bars that said ADD and SUBTRACT. I learned about addition and subtraction puzzles. That you had to do problems that had to equal something with both addition and subtraction. I am happy with this portfolio product because you do something with addition and subtraction. Next time I will try to do something more challenging and harder. I did well on this because there was a tricky problem on number 3. There were two number that were tricky but I got it right because the problem was 95-40 but 95-40 was backwards so I figured out the answer was 55.
