### Mathematics Grade 7 (3111) VA

Mathematics Grade 7 (3111) VA is designed to prepare junior-high students for Pre-algebra. This course focuses on strengthening needed skills in problem solving, number sense, and proportional reasoning. It also introduces students to rational numbers, equations, and geometric concepts. Students will begin to see the "big picture" of mathematics and learn how numeric, algebraic, and geometric concepts are woven together to build a foundation for higher mathematical thinking.

• Integers: Students will learn how to locate, add, subtract, multiply, and divide integers to solve word problems, as well as compare integers using absolute value and evaluate numerical expressions using real number properties and the order of operations.
• Fractions: Students will understand how fractions can be written into other forms without changing their value, and how to add, subtract, multiply, and divide with positive and negative fractions.
• Decimals: Students will explore how to rewrite fractions as decimals, express small and large numbers with scientific notation, and use positive and negative decimal numbers to solve mathematical and real-world problems.
• Patterns and Equations: Students will learn how to translate words into equations and use them to solve mathematical and real-world problems.
• Ratios and Proportions: Students will explore how to use ratios to compare numbers, solve proportions, and convert between percent, decimals, and fractions.
• Probability and Graphing: Students will be able to determine the probability of an event, as well as create a graph of an additive or proportional relationship.
• Data Analysis: Students will learn how to display and interpret statistics using histograms, stem-and-leaf plots, and other graphical means.
• Geometry: Students will explore properties of triangles and quadrilaterals, including similar figures, and transformations on the coordinate plane.
• Measurement and Area: Students will learn about finding perimeters and areas of different polygons in preparation for finding measures of solid figures.
• Surface Area and Volume: Students will explore three-dimensional figures and how to find their surface area and volume.
