I gave this book to my grandson who is 2 years and 10 months old. I had no idea if he would like the story as it is not illustrated in colour. He absolutely LOVES this book. He wants it read 2-3 times in succession. I have bought him Square and Circle but will wait until he is able to visit so I can read it to him.

I love mathematics – with a particular interest in Shape and Symmetry. So, how could I resist an illustrated book called “Triangle”. Although I am a little older than the target audience of 3 – 7 year olds, I really enjoyed this book, and especially the illustrations. The main character is an isosceles (yes, of course I measured the sides) triangle, who lives in a triangular house, in an area filled exclusively with triangles of all sizes (but no scalene or right-angle ones). Being a liberal triangle, he has non-triangular friends, in particular one masquerading as a square (actually a rectangle, but I expect most children will not get out their rulers to check). Triangle wants to play a trick on Square. Actually, quite a nasty trick. He plays on Square’s fear of snakes. Square retaliates by making Triangle scared. Was his retaliation planned – or just a fortunate (?) coincidence? Not really a great lesson for children – how to terrify your friends by using their greatest fear, and validating revenge (deliberate or not). But, on the plus side – they will learn about shapes, and how you cannot get a square through a triangular hole (unless it goes sideways – something for the next lesson).
