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.

Description

With Geometry Pad you can create fundamental geometric shapes, explore and change their properties, and calculate metrics. The shapes are displayed 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, hyperbola.
- Tools to create medians, altitudes and bisectors in a triangle.
- Tools to create special triangles and quadrilaterals: right, isosceles, equilateral, square, rectangle, parallelogram and rhombus.
- Two additional ways to create an ellipse: by center, end of a major axis, and a point on the ellipse; by focus points, and a point on the ellipse.
- Compass tool to plot arcs with an easily adjustable center and radius.
- Pencil tool to draw freehand annotations.
- Text annotations and labels with mixed-in metrics such as length, angle, perimeter, equation, etc.
- Transformation tools: rotation, reflection, enlargement, translation.
- Create lines and triangles with predefined parameters such as equation of a line, and angles or sides of a triangle.
- Insert images into the document.

Each shape has a set of customizable properties such as color, width, background, etc. Shape metrics are automatically calculated and presented along with shape properties. Some of them are editable such as point location, line length, circe radius, etc.

Snapping is deeply integrated into the application. Snap-to-grid and snap-to-objects allow for precise constructions. Additionally, lines can snap to parallel, perpendicular and tangent lines. Snapping can be easily turned on/off in the quick snapping settings window.

Documents can be saved to your device, iCloud or to Dropbox. Export formats include PDF and image.
