Photo interpretation using Jigsaw planet

Learned this from Lesson posted on edumall by Gerald Tay. http://subjects.edumall.sg/cos/o.x?c=/subjects/pagetree&func=view&rid=6755 (you must login to edumall to see this) He actually made use of the jigsaw planet to create jigsaw puzzles online to stimulate the student's interest in the learning of the topic "Geography of food".

The jigsaw puzzle is quite an interesting tool - I will actually use this in photo interpretation for the topic on coastal studies - http://www.jigsawplanet.com/?rc=showpuzzle&pid=330ea41ef34d&ret=%2F The teacher create the puzzles online and the students will have to highlight the main features on the photographs and relate them to what is being taught - eg. landform, process, coastal protection etc.

Play the "FB IMG 1554079059390" puzzle! https://www.jigsawplanet.com/?rc=play&pid=38ebac73ffc7

What are the coastal features shown in the photograph? How are they formed? 

Which type of waves are associated with the formation of the features shown in the photograph?

Quite a number of teachers are also using it as clues for digital escape room!

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:
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

Can you move the animal to the correction direction?
