In The Shapes of Algebra, students will explore the relationship between algebra and geometry. Through this exploration, students will work with equations for lines and curves, and will develop an understanding of how systems of equations and inequalities can help solve problems. Students extend their earlier work in algebra and geometry by making connections between them. For example, students connect the idea of the Pythagorean Theorem to the coordinate equation for a circle, and connect properties of polygons to slopes of lines.
