One of my students (well, truthfully, slowly, every kid in my class) has been reading Babymouse Goes for the Gold. One of life's greatest mysteries gets solved in that book: where do all those goggles go? (It's kind of like how socks lose their mate.....swimmers lose their googles!)
We figured it out....there is an octopus on the bottom of every pool hoarding all the lost goggles.....true story!!
