If your students are going to research Reptiles on Pebble Go, you will love this product. There are 5 Reptiles in all including alligators, crocodiles, snakes, lizards and turtles. You can have them research all of them and put them in a booklet or just choose one.
PebbleGo is a paid subscription. If you do not have access to this, you might not want this product. I am not affiliated with Pebble Go, but love it!
