I've updated this post with pictures of my new fishies! See below for the chant that goes along with this one--though now that I've made this big new set, I can see lots of other ways to use these, similar to ways we use my Mitten Match set...Buy this set at my Etsy shop: https://www.etsy.com/shop/FlannelBoardFun
This is a set I made many years ago. The fish are cut from sheets of foam. I drew them with coordinating colors of marker on the foam and then cut them out, and stuck a square of velcro on the back of each one. I think this probably works best in a classroom, where the teachers know the names of all the children--not sure how valuable it would be for librarians, unless you know your group well enough that you know every child's name... It definitely works well for me when I have a smaller group of children, so there's not a long wait for anyone to come up and take their fish.
With my new found skills and insight (!) I will be re-making this set using felt (no little velcro squares to tempt the children to peel, peel, peel), and I will make the fish much bigger. These are fine for small group time, but bigger is generally better. I'm not sure why I always made my story/game pieces so small in the past. What was I thinking?
