Problem solving applications are addressed using the metric system, as well as exploring data in tables. This unit introduces students to the concept of fractions as rational numbers. Topics includeusing rational numbers in equations and changing rational numbers to decimals. Students learn to solve two-step equations, and to identify and solve inequalities. The coordinate plane is introduced in this section is a useful tool for visualizing the parts of an equation.
Students learn to find the area and the volume of many figures by using formulas.
In addition they learn to recognize the relationship among different figures. The concept presented in this section focus on square roots, right triangles, the Pythagorean Theorem, and trigonometric ratio. Students are introduced to the concepts of statistics and probability. Different types of statistical data are evaluated as well as calculating the probability of an event. An introductory section in which students learn to identify and simplify radicals.
