Mission #3: Collaboration Nation

I know that this is a week late, but my obligations as a  wife and my obligations as a mom during soccer season always come first in my life.  With the said, I want to say that I LOVE the mission challenges!  This summer I became very discontent in how I was teaching.  I still loved my job, but I wanted to be better.  Thus began my search online to find something.  I didn’t really know what I was looking for but I stumbled on some great blogs, which gave me a start in the MTBoS.  I was hooked!  I lurked and I “stole” and even participated in a few twitter chats.  Then the mission challenges came.  It stretched me even more!  It was the push I needed.

Mission #3 gave a list of sites to explore and then asked us to pick one of the sites to blog about.  There were many good sites, but the one that spoke to me was Math Mistakes.  I often do this in my class, but it was great to see a site dedicated to this idea.  It made me realize that I need to be more intentional about this.  I really believe students learn by looking for mistakes because they already have to know how to do the problem to see what is wrong in the problem they are looking at.

I really like how this site it broken down into different grades and common core standards.  In fact, it helped my to find a few examples that I will use in my DO NOW this week because they deal with the topic that were are covering in class.

As I was grading my Algebra I tests, I noticed the following mistake being repeated on quite a few tests:

I am going to put this example up on the board on Monday for my Algebra students to discuss.  I’m hoping that they will see on their own that an answer of “1” is not Identity.  If you have any suggestions or comments, I would love to hear from you.
