During our Japan study in Geography, we made Koi fish.
Using a fish template I found online, we cut (and by "we", I mean "me") out a bunch of circles from origami paper. (Does that make it a DOUBLE Japanese craft? Yay, Mom! Two points!)
Then we pasted to our heart's content. We also added a little bling, using aluminum foil, and added some ribbon streamers. Fun, pretty, and educational. Three more points for Mom!
