Comments on: Real-World Math That Isn’t Real To Students /2013/real-world-math-that-isnt-real-to-students/ less helpful Thu, 21 Nov 2013 13:34:54 +0000 hourly 1 https://wordpress.org/?v=6.8.2 By: Sue Hellman /2013/real-world-math-that-isnt-real-to-students/#comment-1113715 Thu, 21 Nov 2013 13:34:54 +0000 /?p=18174#comment-1113715 I’ve been thinking about the title of this post and wondering how this problem fits. I wonder if it to kids, despite the fact that the problem might come from a real context, it would seem contrived rather than authentic. I’m not sure that working on this question would either excite their natural curiosity enough to make them want to pursue a solution or go some distance to settling the question ‘how will does this math connect to my real life?’. There’s a difference between math people seeing math questions in ‘real’ situations and moving kids towards thinking of math as a tool or set of processes they can easily & naturally engage to make their lives better or better understand what’s going on in the world.

Although Vintage Ports can be enjoyed when young, they will improve for many decades in the cellar and are among the most long-lasting of all wines.

I wonder what their definitions of improve and many are here.

So kind of a fun graph. Really calls into question the definition of “real,” though.
