Teacher Commentary

Almost all of the lessons that we do, like formal lessons, are embedded in a story. That means that because they [my students] get attached to the story there's a character, there's a situation. They remember stories. They don't remember, "Do you remember the day we talked about these numbers?” When their thinking is attached to a story we’ve thought about before, it makes a lot more sense to them because it's nothing new. It really isn't. It's the same thing with this little twist.
