In ‘how we organise ourselves’ UoI, Grade 3 starts with reading a book ” One Hen How One Small Loan Made a Big Difference” by Katie Smith Milway. This book tells about micro finance in a small village in Africa. It’s very good start to see, think and wonder about demand and supply. Then students discuss the response of the story and start to find out what kind of demand from users in the library that can be supplied by the school and librarians.
