In Grade 7, instructional time focuses on four critical areas:
- Developing understanding of and applying proportional relationships.
- Developing understanding of operations with rational numbers and working with expressions and linear equations.
- Solving problems involving scale drawings and informal geometric constructions, and working with two- and three-dimensional shapes to solve problems involving area, surface area, and volume.
- Drawing inferences about populations based on samples.
