So this week's Mission (number 2 for those keeping track at home) over at Explore the MathTwitterBlogosphere was to use my Twitter account, @LauraVHawkins, for math good. And now, I reflect!
One thing that I learned to appreciate was the power of the hashtag. Not just to be clever, it turns out. Adding #MToBS to the end of my tweets made them reach a whole new audience. Look and see my most successful tweet (by some measures):
Tweeting a conversation is a bit too quick for me right now, though. I replied to a tweet about using the textbook less in class, and they replied back to me, and I... let it just lie there. And it seemed too lame to respond a day later, so...
Oh, but it was interesting to spend the week in a "How could I Tweet this?" state of mind. I do that sometimes with Facebook. When something super cool happens that I want to tell someone about, I start thinking about the status update I may write. Last weekend, we went to an amazing brunch at Lazy Bear underground restaurant. Not only was I dancing in my seat at the deliciousness of every course, (because there were so. many. courses), but I also took a picture of each course.
Want to see? Of course you do.
Here's one attempt (inspired by 2 absent student). How do we find the solution to this problem using the rectangle model? (Where 2y^2+2y is the area of a rectangle, and 2 is the "length" so we just need to find the width.) I sadly didn't record it right the first time, though. So this video is missing the reactions of the first time around, but still cool. And that is what I will leave you with. Happy Weekend!
