Sketchpad, also known as Geometer's Sketchpad, is a world-renowned software for teaching mathematics. You can use Sketchpad for geometry modeling, measurements, graphing, and more. Additionally, Sketchpad boasts outstanding features such as projection effects, animation effects, sound effects, making it the most comprehensive math learning software you've ever known.
How to Use Sketchpad
Firstly, ensure you successfully install the Sketchpad software on your computer: check out how to install Sketchpad here.
Step 1: Sketchpad's interface is highly intuitive and straightforward, enabling users to quickly grasp the software.
- 1 - Toolbar: Contains tools to create, draw, modify, and edit objects in Sketchpad, such as the mouse pointer, point, draw a circle, draw a rectangle, draw a line,....
- 2 - Pointer:
- 3 - Sketchpad area: is the working area of the software, the display area for initializing, drawing shapes, formulas,......
- 4 - Menu bar: Contains a list of the software's executable commands.
Step 2: Toolbar: Sketchpad is equipped with basic and comprehensive building tools for you to freely draw and construct geometry.
- 1: Translation Arrow Tool (Selection Tool): Used for selecting objects on the Sketchpad area. This tool comprises three functions to resize objects: translate, rotate, stretch.
- 2: Point Tool: Used to create points.
Step 3: Guidelines for drawing geometry with Sketchpad
To create more accurate drawings, matching your desired dimensions, consider establishing a coordinate system by selecting Graph in the Menu bar, and then choosing Show Graph
- Drawing Points: Choose the point tool, move the mouse to the Sketchpad area, and click to create a point.
- Drawing Circles: Select the compass tool, move the mouse to the Sketchpad area, and click. The point created will be the center of the circle; you drag the mouse to set the radius.
- Drawing Segments, Lines: Choose the straightedge tool, move the mouse to the Sketchpad area, and select 2 points on it.
- Drawing Shapes: Choose the shape drawing tool. For example, to draw a triangle, create 3 points anywhere on the Sketchpad area with the desired dimensions and move the mouse back to the starting point to finish. You do the same for drawing a square, rectangle, quadrilateral, pentagon, hexagon,....
- Adding Text: Select the Text tool and double-click in the Sketchpad area to start writing.
- Marking: Choose the Marker Tool and start marking as desired.
Here is a guide on using Sketchpad's basic geometry drawing tools. We hope this software provides teachers with a lesson planning tool and students with an exciting math learning experience.
