Which One Doesn’t Belong?

UPDATE 5/20/2020:  I found some more WODB images, and posted the link here if you are interested!

I just love the people I follow on Twitter.  I get so many great ideas that would probably take a decade to reach me if it weren’t for the #eduawesome people who share resources regularly.

The other day I caught a tweet from @JStevens009 that had a link to a mysteriously named Google Slides presentation, “WODB?”  I opened it to find 52 slides that each showed four pictures.  (John stated that a colleague who doesn’t tweet had shared the presentation.)  Doing a little more research, I found the @WODB Twitter stream, which led me to the WODB website, “Which One Doesn’t Belong?”

The website was created by @MaryBourassa, but includes submissions from many people.  The basic premise is to provide 4 pictures that share some attributes, but not all.  Your mission is to explain why each one doesn’t belong, and to support your answer. There are some that are more obvious than others, and that’s where the fun comes in!

For example, in the image  above, it is obvious the nickel does not belong because the rest are pennies.  The bottom right picture does not belong because it’s tails and all of the rest are heads.  The bottom left one does not belong because it is the only one that does not add up to 5 cents.  But what about that first picture?

Seriously.  WHAT ABOUT THE FIRST PICTURE?!!!!!!!

Someone tell me what the other 3 pictures have in common that the first one doesn’t. I can’t figure it out.

And it’s driving me crazy.

I just teach gifted students; that doesn’t mean I am one!
