A teacher's geometry box is a set of tools and instruments used by teachers for teaching geometry concepts to students. It typically includes items such as rulers, protractors, compasses, triangles, and other geometry tools that help to draw and measure different shapes and angles. The box may also contain manipulatives such as geometric solids, tangrams, or pattern blocks, that allow students to visualize and explore geometric concepts in a hands-on way. The goal of a teacher's geometry box is to provide teachers with the necessary tools and materials to effectively teach geometry and to engage students in the subject matter through interactive and visual learning activities.
