Draw, construct, and describe geometrical figures and describe the relationships between them. Solve real-life and mathematical problems involving angle measure, area, surface area, and volume. Understand congruence and similarity using physical models, transparencies, or geometry software. Solve real-world and mathematical problems involving volumes of cylinders, cones, and spheres.
Ratio & Proportional Relationships
Analyze proportional relationships and use them to solve real-world and mathematical problems.
Apply and extend previous understanding of operations with fractions to add, subtract, multiply and divide rational numbers. Know that there are numbers that are not rational and approximate them by rational numbers.
Expressions & Equations
Use properties of operations to generate equivalent expressions. Solve real-life and mathematical problems using numerical and algebraic expressions and equations. Work with radicals and integer exponent. Understand connection between proportional relationships, lines, and linear equations. Analyze and solve linear equations.
Statistics & Probability
Use random sampling to draw inferences about a population. Draw informal comparative inferences about two populations, investigate chance processes and develop, use, and evaluate probability models.
