Creating Mathlets with Open Source Tools, Markus Hohenwarter and Judith Preinder

The GeoGebra applet options are accessible in the export dialog for dynamic worksheets (see Exporting the Dynamic Worksheet). By selecting the tag "Advanced" you can check which of the following options the dynamic figure on your dynamic worksheet should include. ## Reset IconBy checking "Show icon to reset construction" you can include a reset icon into the dynamic figure of your worksheet. The icon will be located in the upper right corner of the interactive applet. By clicking on this icon students can reset the applet to its initial state. ## ToolbarThe applet option "Show toolbar" allows you to display the GeoGebra toolbar within the applet of your dynamic worksheet. Thus, the tools can be used to modify or extend a given construction. |

In order to display the input field at the bottom of the interactive applet you need to check "Show input field". This option allows your students to modify the dynamic figure by using the keyboardby to type in algebraic expressions.

*Example*: See the second example worksheet Equation of a Slope Function

*Tip*: You might need to increase the height of the interactive applet to provide additional space for the input field.
