Contour with edumedia

You can also show the interactive version of the contour simulation. Very cool and free for use now.
https://www.edumedia-sciences.com/en/media/528-contour-maps Used that to show the students during the HBL.

Measuring Grid Bearing

Sharing how I use the simulation (Geogebra) to teach grid bearing.  You can also find the simulation in the map reading lesson shared in the SLS Community Library.
You can find the embedded simulation on my Google site -
https://sites.google.com/a/moe.edu.sg/sec-1-geog/geographical-skills/3-topographical-maps

A simple demo on how to use the simulation.

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".

Compass direction and Compass bearing simulation 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 created by Wei Sern:

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

Can you move the animal to the correction direction?

Interactive media for map reading on SLS

So happy to find that interactive media from ETD is now included in SLS. Would really hope that the older interactive e.g. grid reference - fun with building and grid bearing - flying a plane are also included! The only draw back with the existing one is the absence of 4-figure and 6-figure grid reference. However still love the games Sailing with bearing and Quest of Arudra Island.







Added the interactive media on lesson review - "How to read a map (part 2) features of a map."



Added the interactive media on the game  "Quest on Arudra Island"



Added the interactive media on the game  "Sailing with Bearing"

To overcome the issue of the lesson review not showing the 4-figure and 6-figure grid reference, thinking of using the thinking routine to get the students to draw it out.
