Here's a fun printable for you with frogs from My Cute Graphics. I used my scrapbooking program to put the numbers on them. Right now, there are only 5 frogs because I intend to use them for the "Five Speckled Frogs" song. Another way to use them would be to place them in a row, then to have the child put black pom poms on each frog to represent how many flies he ate.
I'm find of on a frog and pond kick right now. I have many more ideas in my head that I'd like to share in the future. Stay tuned!
