The Great Pet Sale by Mick Inkpen
Publisher: Hodder Children's Books
The sad-looking animals in the pet shop sale are all priced between 1p and 10p (apart from the komodo dragon at 25p). The rat with half his whiskers missing says, 'I'm a bargain, I'm only 1p. Choose me!'
With the pictures reproduced on card, or toys priced similarly, children could choose which pets they might buy for 10p: for instance, they could have the 2p terrapin, the 3p turtle, the 4p tortoise and the rat, or two 'things beginning with P' at 5p each, such as the pelican and the platypus. They could then extend this activity by spending different amounts
and adding in new pets and prices.
