This edition provides the same great mastery approach to math that we know and love from Math Mammoth. The revised edition of Grade 5 has streamlined lessons, making some lessons optional, and has rewritten entire lessons in chapters 1, 2, 5, and 9. The lesson concerning circles has been removed and longer lessons in chapter 1 have been made into two separate lessons. These revisions have been made to help create a more focused presentation. The same four components (2 worktexts, test booklet, answer key) are specific to this edition. Areas of study in Grade 5 include: the four operations with whole numbers, decimals, and fractions; along with statistics, graphing, problem solving, and geometry. ~Rebecca
