Ezra & Mr. Bignall's Disappearing Maths Class

This is a journey for children of 10+ into the history of numbers and how it took humans 50000 years to learn how to count from one to ten. It is a wild story about a school boy called Ezra and his first day in his new school. His teacher seems dull and boring but transforms into a bear and takes his class on a journey through space and time to discover some of the yuckiest things anbout how people learnt to count.
