I don’t have a picture for this, but every single one of my 4th Graders thought that “average” meant “the most common thing.”
(a) Where do they get this idea from?
(b) Is it a big deal misconception?
(c) How do you create a need for something besides “most common”?
(I think I have my own answers for (a) and (c), but I’m more curious to know what you guys all think.)
