What makes math difficult? No(n)sense!

Wrap your brain around this picture. Makes perfect sense doesn't it? I just checked the figures on my calculator and the total is right. So that means that the Gold Hill folks were pretty good at addition. But unfortunately making sense out of things wasn't one of their strong points.

This sign - well actually one similar to it - gave me an idea for what I did (or you can do) with a 6th grade math class. (Click here.)

@climeguy and for algebra 1 you could write 2x + 3y + 4z = 9xyz? and ask how this relates to the picture. (Sent by @scsocha)

    Yes. Great idea! Challenging students to deal with their misconceptions in this way is very powerful.
