As students enjoy the stories, they encounter one maths word problem after another, and they learn to think, calculate, and come up with the right answers. Lostis Marbles, the mayor of Mathopolis, loves numbers but usually gets them all mixed up-until two Superheroes come to his rescue. They are Elexus Estimator, who is quick at estimating volume, height, weight, and the like ...and Maverick Measurer, who values accuracy above all else when making maths calculations. As children read the stories, they too will work out answers to the mayor's many problems.
