Math Monsters: Book 1: The Rise of the Shape Sorcerer

Jay and Erin are secret agents tasked with preventing math monsters from crossing into our universe. When their headteacher is taken over by one such monster, every pupil across school is transformed into a shape and forced to sit test after test after test forever! Can Jay, Erin, and their friends stop this monster before it's too late?
Written by a maths graduate and primary school teacher, the math monsters' series is designed to help tackle anxiety around maths for children, and maybe even their grown-ups! Each book focuses on helping children to realise that they have the strength to achieve anything with enough determination, and that they need to be kind to themselves and not let a fear of going wrong hold them back. That way, they will all join Jay and Erin as secret agents against the evil monsters! Additionally, the books reinforce some of the learning and vocabulary taught in schools.
