(Grade K) Mathematical Reasoning helps students devise strategies to solve a wide variety of math problems. This book emphasizes problem-solving and computation to build the math reasoning skills necessary for success in higher-level math and math assessments. This book is written to the standards of the National Council of Teachers of Mathematics. The Level A book is a complete curriculum for Kindergarten grade level. These highly effective activities take students far beyond drill-and-practice by using step-by-step, discussion-based problem-solving to develop a conceptual bridge between computation and the reasoning required for upper-level math. Activities and units spiral slowly, allowing students to become comfortable with concepts but also challenging them to continue building their math skills.
