Geometry Board: Interactive Tool for Teaching Geometric Constructions

About this classroom tool

The Geometry Board is an interactive classroom tool designed to support teaching and learning of geometric concepts through digital construction and measurement. It allows teachers and students to draw and manipulate points, lines, line segments, rays, circles, arcs, and polygons directly on an interactive smartboard.

This tool is particularly useful for exploring Euclidean geometry by constructing intersections, midpoints, parallel and perpendicular lines, as well as angle and perpendicular bisectors. It also includes digital instruments such as rulers, protractors, set squares, and compasses to measure lengths and angles accurately, enhancing understanding of geometric properties and relationships.

By integrating these features, the Geometry Board enables dynamic and visual presentations of geometric concepts, making abstract ideas more accessible and engaging for learners across all grade levels.

Key concepts

• Points, lines and segments — fundamental elements of geometry used to build figures and understand spatial relationships.
• Geometric constructions — creating precise figures such as perpendicular bisectors and angle bisectors using digital tools.
• Measurement tools — digital rulers, protractors, and compasses for accurate length and angle measurement.
• Polygons and circles — constructing and analysing shapes including triangles, arcs, and circles.
• Parallel and perpendicular lines — understanding and constructing lines with specific orientation properties.

Using it in the classroom

• Use as a starter activity to review basic geometric terms by constructing points, lines and angles together as a class.
• Demonstrate geometric constructions step-by-step on the smartboard to model problem-solving strategies.
• Encourage students to explore properties by measuring lengths and angles of constructed figures during lessons.
• Set homework tasks where students replicate constructions or create new figures using similar digital tools at home if available.
• Use the tool for formative assessment by asking students to construct specific figures or solve geometric problems interactively.
