7th Grade Math

By the end of seventh grade, students should be able to demonstrate the following math abilities, based on the Common Core State Standards. Many skills are worked on throughout the year and build on each other.

Algebra

• Add, subtract, multiply and divide positive and negative numbers, including fractions, to solve problems. Show the operation on a number line.
• Use proportions to solve problems, like simple interest, markups and markdowns, tips, etc.
• Makes graphs of proportional relationships.
• Solve multi-step real-life and mathematical problems involving positive and negative numbers, fractions and decimals.
• Solve equations and inequalities that represent real-world problems. (Inequalities are like equations, only they have a greater than (>) or less than sign (<) instead of an equal sign (=). For example, as a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. The inequality would be 50 + 3s > 100.)

Geometry

• Solve problems involving scale drawings of geometric figures.
• Know the formulas for area and circumference of a circle and use them to solve problems.
• Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals , polygons, cubes, and right prisms.

Statistics and Probability

• Make generalizations about a set of data given the mean or median and the spread of the data.
• Understand basic probability concepts.
