First, students will learn to connect the ideas of ratio and rate to multiplication and division. If they can view ratios and rates as originating from and extending pairs of rows or columns the connection with multiplication and division allows students to expand on their skills.
Second, the students will complete their understanding of the division of fractions and of the system of rational numbers, including negative numbers. They will understand the order and absolute value of rational numbers and the location of points on the four quadrants of the coordinate plane.
Third, the students will learn to write and understand expressions and equations. The students will become able to write equations and expressions that describe a given situation. They understand that the solutions of an equation are the variables that make the equation true. The students learn to solve simple one-step equations and can create tables to describe the relationships between values.
Fourth, the students will begin to develop an understanding of statistics. They will understand that data distribution may not have a definite center and that different methods of measurement can provide different values. The students will learn how to use and calculate the mean and median of a group of numbers. They learn how the measurement of variability helps to describe a set of data.
