Paper Magic: Circles to Square


Mixing in mathematics and magic again with this geometry puzzle from 'What We Do All Day' http://www.whatdowedoallday.com/2015/06/geometry-magic.html?utm_source=MadMimi&utm_medium=email&utm_content=Can+Your+Kids+Turn+2+Circles+into+1+Square%3F&utm_campaign=20150616_m126214658_Can+Your+Kids+Turn+2+Circles+into+1+Square%3F&utm_term=geo_magic_fb_jpg_3F1434468503


First I taped the two paper rings together and sliced one ring in half all the way around.
M: "When I cut this circle, what do you think will happen?"
O: "Two circles."

M: "What about when I cut the strip?"
O: "Three circles."

Would you believe, it makes a square?

 
 "What?!"
Framed!
