I had a small sheet of cute little animal stickers so I made a game.
I put the stickers bag in the plastic wrap they came and but drew 'bars' in front of the animals with a permanent marker.
The rules state:
"This is a zoo with 18 animals. But some are double (eg. 2 lions). Help us up the variety by taking out one of the animals which are double and add a sticker with a new animal instead. Let's get as many kinds as possible.
No more doubles? Send home to *name and adress of reciever*"
I hope one of my pals will enjoy this game and have fun with sending it on to other penpallers.
