In the File menu, Export you find the item Dynamic Worksheet as Webpage (html).
In the export window you can enter title, author, date and some text above and below the dynamic construction (e.g. a description of the construction and some exercises). The construction itself may be included directly into a webpage or opened by clicking a button.
Note: don't take too big values for the width and height of the dynamic construction in order to make it fully visible in the internet browser.
Three files are created when exporting a dynamic worksheet:
All three files - e.g. circle.html, circle_worksheet.ggb and geogebra.jar - have to be in one folder (directory) to let the dynamic construction work. Of course, you may copy all three files to another folder too.
Note: The exported HTML file - e.g. circle.html - can be viewed with any internet browser (e.g. Mozilla, Internet Explorer). In order to let the dynamic construction work, Java has to be installed on the computer. You can get Java from http://www.java.com without charge. If you want to use your worksheet in your school's computer network, ask your local network administrator to install Java on the computers.
You can also edit the worksheet's text with many word processing systems (e.g. Frontpage, Word) by opening the exported HTML file.
