This is a one-page, printable crossword about animals. Some vocabulary you could cover using this activity would be: predator, prey, herbivore, mammal, reptile, amphibian, and primate.
There are also some critters to color.
I have other puzzles on a variety of topics at my store CuriousCrosswords. You can also find other fun, free printables on my blog, CuriousCrosswords.com.
I hope you have as much fun using my puzzles as I have making them!
