Interactives using Geogebra

Awesome sharing by Wei Sern from SGLDC on creating interactive exercises in Geogebra. This is useful especially when embedding html code is available end of June in SLS. You can also use the code to embed on Google sites and Blog (like the one below)

Reading compass bearing

https://ggbm.at/hydx8tm2


1. Check the box next to "Use Protractor" so that the protractor will appear.
2. Read the question on where to measure the bearing from.
3. Select "Move compass to A or B" as shown in question.  E.g. point B
4. Drag the protractor and rotate it so that O points to the north. (If the angle is more than 180° then rotate the protractor with 0 starting from South and the read the angle. Add 180°to the reading.)
5. Drag the pin head so that the line intercept with the point it is measuring to e.g.point A
6. Read the angle from the protractor and enter the number into the keypad with the degree symbol.
7. Click on "Enter Check".



If you want to get the code to embed, you need to download the GGB file  (e.g from https://ggbm.at/hydx8tm2)and then upload as your activity in your GeoGebra account. Then in your GeoGebra account you can follow the following steps to get the code to embed in you blog or site:

I have commented earlier how I missed the earlier ETD game of using interactive game to learn compass bearing. Learned from him that compass bearing is also learned in O level E Maths and that he could create the simulation in geogabra.  Students kinestatically learn how angle bearings of one location from another is referenced. It allows the sttudents to move a virtual compass and then input the value of the angle.

The original exercise had some drawbacks when used on a mobile phone, hence he had improved on it by including a virtual customized keyboard which allows the activity to be run on phone browser with better graphics control and interface.

He also mentioned that the protractor tool can be made into a template file and inserted into any existing good quality Geogebra geometry activity resource without too much effort! It can be downloaded from

Amazing application by Wei Sern

He also shared some examples of how others have made Geogebra resources (math) in Chinese.

 Interesting point is that it is possible for existing English based quizzes to be converted to Simple Chinese text quizzes.

There will an easier way of embedding of embedding the geogebra end of June when the embed HTML function is available.

He had shared earlier on how Geogebra is used in Science and Maths.

  1. Thanks for sharing. Such resources are easily modifiable, and the software Geogebra is free and easily accessible and resources mostly on creative commons share alike CC SA licence.
    Definitely very useful to teachers needin good T&L resources with as little effort in prep work.
