An integration of the study of whole numbers and the integers with an approach to mathematics teaching and learning found in the National Council of Teachers of Mathematics' Principles and Standards of School Mathematics and the Maryland Common Core State Standards. Mathematical content includes place value, estimation, conceptual underpinnings of the conventional computational algorithms for whole numbers and extending these ideas to integers. Early number concepts, how students develop number sense, how to judge when student-developed procedures are mathematically sound, common misconceptions and how to address these misconceptions are central to this course.
