This is a simple click and tag site. You look at pictures, answer some questions and click on the center of the penguin. First question is are there penguins or other animals present?
Then, you mark the center of adults, chicks, eggs, or other (non penguins). If there are a lot of penguins, it will tell you after 30 marks that you've done enough and can feel free to move onto the next image. The last question is did you mark all of them or were there too many penguins.
Very simple and straightforward. If your kids can use a mouse, they can do this activity. Boo absolutely loves it. I highly recommend this for meaningful, yet slightly mindless, clicking!
