The GeoGen Shape Generator is a premium teacher-only math tool designed to help educators quickly create high-quality geometry, area, and perimeter practice materials. Registered teachers gain access to a powerful shape-building tool that generates custom rectangles and polygons with accurate side-length labels, optional missing sides, and calculated area and perimeter values.
This tool is ideal for lesson planning, assessments, math centers, and small-group instruction. Teachers can generate shapes with 3 to 8 sides, switch between measurement units, lock shapes to the same area or same perimeter, and create custom rectangles by entering specific lengths and widths. Options for hiding one or two side lengths allow students to practice solving for unknown values.
As a premium resource, the Classroom Shape Generator is available to registered teachers only, ensuring a focused, classroom-ready experience. All generated shapes can be downloaded as high-resolution PNG images, making it easy to add them to worksheets, slides, quizzes, and digital assignments.
