"Westpac is making available maths development app Mathspace to ensure children learn skills that will be useful to them in the future.
Mathspace was designed in Sydney and is based on the school curriculum. It can replace a textbook but is interactive and tailored to the student, and is already used in Hong Kong, Britain and the United States.
Westpac is covering the cost of each $99 download of the app. And for each child who signs up for the premium program and completes the quizzes and tasks, the bank will refund into a Westpac account the $10 weekly subscription fee."
