  1. An interesting comment was posted by CCSSImath about problem #24 on YouTube. I wanted to share it with my blog visitors. And, I agree with this! .. I just wish I had noticed it myself! Thanks CCSIMath!

    Here is the comment ---

    The question is faulty. Answer J shows one combination of possible numbers of each type of animal, but it is not the only possible combination.
    Wording matters. The question "Which list shows THE number…" misleadingly implies there is a unique answer, but there are infinitely many.
    For instance, there could be 16 cows, 4 horses and 2 pigs.
