Book Study - Chapter 2 - Acting on the Data and the Culture of Error

 1.  Right answer tells: Nodding, smiling, answering with a positive response
      (such as yes, great, good job, correct, etc.), giving praise

       Wrong answer tells: Asking "Are you sure?", shaking head, saying "hmmm",
        saying "not exactly", asking if anyone else can help the student out, asking the
        student to look again

2.     "How did you arrive at that answer?", "I see where you are going, but what
        about...?", "You are on the right track..."  

3.    What errors might students make while rounding to 246.74 to the nearest
        hundreds place?

• Rounding to the incorrect place
• Rounding up when it should be down and vice versa
• Dropping the decimal portion completely        
• Rounding the hundred instead of the hundreds place

        I would do a quick review on place values and what each number represents.  I
        would give a couple of simple examples on the whiteboard or screen to do as a
        review as a class.  

4.  How are books organized in the non-fiction section of the Media Center?  Books
     are organized by Dewey Decimal number, then the author's last name.  There are
     posters and signs around the Media Center to signify different numerical
     sections and make it a little easier to find books.

    a.  Potential wrong answers: They are organized by last name, by first name, by
         subject, by title, by color

    b. Students might say books are organized by last name because picture books
        and chapter books are and that could be confusing.  They might say subject
        because they see the posters and signs indicating books are grouped by Dewey
        subject.  Although that is partly right, the author's last name is also important.
