Beast Academy provides a fun, rigorous, challenging, complete curriculum for aspiring math beasts. Unit 3D includes chapters on fractions, estimation, and area.

The Practice book provides over 400 problems ranging from introductory level exercises to very challenging puzzles and word problems.

The Art of Problem Solving folks present: Beast Academy. Proving that any monster can do math, these comically monstrous beasts take you along with them as they face math challenges both inside and outside the Academy. Described as “rigorous, challenging, engaging, and fun” by the publisher, I would expect nothing less from a curriculum designed to ready your child for the demands of MATHCOUNTS and post-elementary AOPS curricula.

There are four parts for each grade level though the series is not all available as of this writing. Each part consists of two books: a Guide and a Practice book. Core instruction takes place in the Guide which is written in colorful, comic-book style and stars a cast of not-quite-cute monsters. Each book is divided topically into three chapters.
