Geometry Pad

Geometry Pad is a sophisticated app that gives students an opportunity to explore geometry independently with a host of tools. With Geometry Pad, users create basic geometric shapes, discover and change their properties, and calculate metrics. Shapes are presented on a scrollable and zoomable workbook with a rectangular coordinate system. The following tools are built into the application: point, angle, line, ray, segment, perpendicular bisector, tangent, triangle, quadrilateral, polygon, regular polygon, arc, sector, circle, ellipse, parabola, and hyperbola. Documents can be saved to your device, iCloud or Dropbox. Export formats include PDF and image.

Working with high school students with developmental disabilities, our reviewer is required to introduce geometry using the NYS Alternate Assessment. The goal is for students to parallel a task that is being used in the "typical" curriculum. One of the goals is for students to put a shape on a coordinate linear graph. Geometry Pad solved this difficult task. The app comes with a preloaded graph worksheet with coordinate points. Students can pick a shape at the bottom of the screen, from square to circle to rhombus.

Next, the app prompts the student to tap two points on the graph. Voila, it makes the shape! Many of my students needed prompting the first few times they used Geometry Pad, but after practice, they understood how to make different shapes. If you are working with students with visual spatial disabilities or dysgraphia this is a great app to help them understand basic geometry in the free version. Common Core Standards: Grades 1-5 Geometry Suggested IEP Goals: When presented with different shapes (e.g., circle, triangle, square, rectangle, rhombus, trapezoid, pentagon, octagon and hexagon), the student will correctly match the shapes to their definition. The student will point to a circle, square and triangle when presented with several mixed geometric shapes.
