The Otago Problem Challenge is a mathematics problem solving competition aimed at Intermediate School children. It is organised by members of the Department of Mathematics at the University of Otago.
Children participating in the competition attempted to answer five questions in 30 minutes. The questions get harder as you go. Question 1 being the easiest and 5 the hardest.
Here's question 4 from todays challenge.
This term we have been focusing on Uno’s Garden’s a picture book by Graeme Base.
Uno's Garden is a rich story that delivers a powerful message through both its words and pictures. The diversity and detail of the illustrations tells a complex story that provides an excellent starting point for children to start considering their impact on their environment and how this can be positive.
The main theme of the book is sustainability. Sustainability is keeping things the same as they are, so if you cut down a tree you then plant a tree to replace it.
The big idea for this terms unit Uno’s Garden is "to understand the need to protect and preserve our local environment”.For this inquiry I am going to explore eco housing concepts then design and explain an eco house of my own
Hopefully at the end of this inquiry I will have a better understanding of the different ways an eco-house can be environmentally friendly and how an eco-house can be constructed without the high cost.

And they were all fantastic.
It was very encouraging and sets us up for years to come, we all enjoyed it so much we would love to go again.
Overview / Storyline
Uno arrives in the forest on a beautiful day at the very beginning of spring and is greeted by a myriad of beautiful, lush plants and the most fantastic creatures he has ever seen. He likes it so much that he decides to stay there.
Uno's decision spells doom for the plants and the creatures of the forest, including the only completely ordinary Snortlepig.
But Uno is wise and sees the future of his children and their children if someone does not act to stem the consequences of civilisation. So he starts a special garden that does not have the vegetables and flowers of other gardens, but allows his children and grandchildren to have hope for their future.
Uno's Garden is a rich story that delivers a powerful message through both its words and pictures. The diversity and detail of the illustrations tells a complex story that provides an excellent starting point for children to start considering their impact on their environment and how this can be positive.
