Once upon a time, more than 20 years ago, my toddler introduced an imaginary friend: a cat called Sitty. She was a member of our family and our storytelling for several years - except one afternoon, when apparently she said she didn’t want to be my child’s friend any more! They made it up.

This original picture book classic has sold over 250,000 copies and is in the Daily Telegraph's top 50 children's books of all time.Sid the cat lives at number one Aristotle Street. He also lives at number two, number three, number four, number five, and number six. However, he is required to be a different cat depending on the house. Slightly older children will appreciate this because at school different teachers require different things. Younger children with blended houses living in separate houses will also get it — the idea that different situations and people require different versions of yourself. Inga Moore has beautifully depicted two British streets. One street contrasts with the other, in a didactic kind of way to be fair — in Aristotle Street the neighbours don’t talk to each other, whereas in Pythagoras Place, one street over, they do.

When Sid is made to take six different doses of medicine I worry for his health. That can’t be good.This is a great book for cat lovers who can appreciate the 90% intellectual and the 10% calculating ways of our fabulous feline family members. Because the residents don’t talk to each other, they don’t realise. But when they do find out, they’re furious. So Sid moves to Pythagoras Place, where people chat with their neighbours, so they know he’s a six-dinner cat, Sid divides his time between six houses in Aristotle Street: six names, six personalities, and six dinners. The Numicon Shapes can be explored in a variety of different ways to encourage children to learn about number. They can also be used in counting and calculation activities. Six-Dinner Sid has also been reviewed by The Canberra Times, [3] Publishers Weekly, [4] School Library Journal, [5] Horn Book Guides, [6] Five to Seven, [7] and Magpies. [8]
