This course is designed to formalize and extend the mathematics that students learned in elementary school and sixth grade. Students extend their understanding of operations with rational numbers and develop their proportional reasoning in various contexts. Students develop their algebraic thinking through reasoning with diagrams, expressions, equations, and inequalities. Students build on their understanding of geometry and measurement, solving problems related to scaling, area, surface area, and volume. Students extend the understanding of statistics by drawing inferences about populations based on samples. Throughout this course, students will persevere in problem solving, engage in mathematical arguments, model mathematics, communicate with precision, discern patterns and structures, and analyze the whole situation and work with the details. Students will utilize both content and practice in the context of real world situations.
