In 7th Grade Math, you will start by studying scale drawings in Unit 1. Scale drawings help support Unit 2 and Unit 4 which is about proportional relationships. It also makes use of grade 6 arithmetic understanding and skill, without arithmetic becoming the major focus of attention at this point.

Geometry and proportional relationships are also interwoven in the third unit on circles, where the important proportional relationship between a circle's circumference and its diameter is studied.

By the time you reach the fifth unit, you will work on operations with rational numbers, both positive and negative. The work on operations on rational numbers, with its emphasis on the role of the properties of operations in determining the rules for operating with negative numbers, is a natural lead-in to the work on expressions and equations in the next unit.

Students then put their arithmetical and algebraic skills to work in the last two units, on angles, triangles, and prisms, and on probability and sampling.
