7th Grade

Mathematic 7 builds on Grade 6 work by extending students' understanding of ratio to a more formal understanding of the rate and its application with percentages. Students extend their understanding of operations with rational numbers to include negative rational numbers. Students then continue the work they started in Grade 6 in writing expressions and equations, laying the groundwork for their Grade 8 work with functions.

The course then turns to more formal methods for writing and solving multi-step equations and inequalities. Students also build on the Grade 6 work with proportional reasoning as they learn to scale 2-dimensional figures and to apply proportional reasoning to probability and statistical situations. Students gain fluency with the area, surface area, and volume of 2- and 3-dimensional shapes composed of polygons, including right prisms and pyramids. They use the formulas for the area and circumference of a circle to solve problems and understand the relationships among the components of a circle.

The final unit of study lays the groundwork for high school Geometry as students investigate informal proofs of key geometric relationships among triangles.

There is a focus throughout the course on mathematical processes and practices. These practices should become the natural way in which students come to understand and do mathematics. While, depending on the content to be understood or on the problem to be solved, any practice might be brought to bear, some practices may prove more useful than others. In Grade 7, reasoning and developing viable arguments are particularly important, as are modeling, the use of strategic tools, and precision of language.
