Seems like there is a lesson on fractions here. How many watermelons are there in the first picture?
Another thought: This could totally be done as a number talk!
Another thought: I wonder how some of these pictures are analogous to the border problem? Is there something about making the pictures larger or smaller that could lead to a generalization? This one seems like it would work well for growing/shrinking/generalizing.
Another thought: This one is hecka cool for kids to think about visualizing how shapes get dissected and put back together in 3-D.
UPDATE:
My colleagues and I included some of these photos for Number Talks in our Math 6 curriculum. (For those who are unfamiliar with Number Talks, I highly recommend learning more!) We called them "Tasty Number Talks" and they have been a huge hit with teachers and students. Unfortunately I have not yet gotten to see a Tasty Number Talk in action, but I hear good reviews! I wonder what the artist Sakir Gokcebag would think about his art being used for math class...
