Geometry is frequently challenging for students because every problem involves a figure that students must use to solve the problem. Each new concept is introduced in an easy to understand way, using example problems that are worked out step-by-step and line-by-line to completion. This program teaches students how to solve problems involving circles. Radius and diameter are introduced, followed by a discussion of how to calculate the circumference and area of a circle. Numerous problems are worked to give students practice with these concepts.
