This book, the most recent curriculum unit from the Center for Gifted Education, provides gifted and advanced learners challenging activities related to the CCSS for Mathematics. The 24 lessons cover math content for grade 4, including operations and algebraic thinking, numbers and operations in Base Ten, fractions, measurement and data, and geometry. Each lesson follows a predictable structure and includes a teacher page that outlines the CCSS and mathematical practices covered, estimated time, key terms, materials, and objectives; a challenging activity to allow students to explore the concepts in depth; practice problems; and an assessment similar to CCSS-based grade-level standardized assessments.
