7.1 Scale Drawings
Students combine their Grade 6 ratio work wtih their geometry knowledge as they use, interpret, and make scale drawings.

Students develop understanding and algorithms for the larger set of rational numbers, specifically negative rational numbers, using the numberline as a major supporting representation.
Students investigate a variety of contexts that can be represented as proportional relationships and others (e.g. linear relationships that take the form of y=mx+b) that can not be, establishing that proportional relationships are special in mathematics.
Students continue their work in 2-dimensional measurement by extending their previous area and perimeter work with polygons to area and circumference of circles.
Students investigate whether sets of angle and side length measurements create unique triangles, multiple triangles, or fail to create triangles at all; they also apply angle relationships to solve problems.
Students investigate compound probability and consider their intuitive models of probablity. They also connect probability to statistics by using random samples to describe a population and using measures of central tendency to support inferences.
