The animals that my son chose for these word families were a pig and a bee. He really likes choosing the animals and while I see no logic in his choices, I'm sure they totally work in his cute little 5 year old brain.
You can get these printables for free by right clicking on the images below and selecting save or print from the pop up menu.
I suggest printing these on white cardstock, they just work so much better than regular (thin) paper. You can use these in your classroom or at home, but please don't share the file - just send all your teacher friends here!
And if you feel like getting something else while you're here, check out this super cute nerdy animal clipart set!
