### Description

Numbers are everywhere. When we are shopping we are faced with decimals. In our cooking, we work with fractions. When it comes to the stock market, we can see positives and negatives. In this course, we will we focus on these rational numbers and understanding the operations when working with them. This course includes five units with rational numbers used throughout.In Unit 1, we will build on our skills with integers, decimals, and fractions, with a focus on the properties that are at the heart of adding, subtracting, multiplying, and dividing. These skills are used to help build an understanding of proportional relationships through ratios, rates, and scale drawings, and similar figures in Unit 2.Variables will join the rational numbers in Unit 3 so that real-life mathematical problems can be expressed and solved. Mathematical reasoning will continue to grow in this unit as simple equations and inequalities are used to model different real-life scenarios. Two-dimensional and three-dimensional shapes will be used to solve problems involving surface area and volume in Unit 4. Rational numbers will work in conjunction with formulas as we continue to model real-life problems with mathematics.Finally, in Unit 5, rational numbers will be used to analyze populations and make predictions. This course extends many of the units from grade 6 and builds further mathematical reasoning to prepare you for the content of the grade 8 math course.
