A unique approach to the study of maths, conservation, history and storytelling this picture book tells the story of a bird, the takahē, which was once thought to be extinct. The story starts before the arrival of any humans and with each turn of the page we see the affects of man, animal, development, and ultimately conservation, as the mathematical equation deducts and adds to the population numbers. The maths equations are given as much importance as the text.

To structure the narrative of an endangered bird around a series of maths equations is genius. You get to add and subtract as you read, and to grasp how important conservation is in Aotearoa.

Excellent illustrations that give the birds and scenes life. Takahē Maths is a brilliant book.
