Topic: Polygons – Sum of Exterior Angles
Level: Secondary 1 Express
Blog Title: Polygon – Sum of Exterior Angles (http://polygons-exteriorangles.blogspot.com/)
Purpose:
- To enable students to practice independent learning and for teachers to use blogs as a form of assessment of students' learning
Description of Activity:
- Students will learn about the concept of Sum of Exterior Angles in a Polygon through their independent self study using the internet links and websites provided
- Students will give comments on questions posed on the blog
- The comments will allow teacher to assess students' learning
How the blog is used:
- Web links and sites for independent learning
- Questions (with right/ wrong answers) for students to make comments
- Diagrams for questions

an interactive activity.
A good way of investigating the properties of polygons.
Very good for enrichment. Pupils should be encouraged to be independent learners.
Prior to the start of the 'module', a polygon can be posted in the blog to get pupils to guess the sum of angles of a polygon. For example,
>> Image: An Octagon <<
>> Ali said the sum of angles in the polygon is 360 degrees. Do you agree? Explain why you agree or do not agree.
Pupils can post their explanations. Some of them may post diagrams to explain.
This can be followed by the websites that they learn about the different polygons as well as the calculations.
Eventually, solving the problems.
Indeed, there is potential for this module to be delivered in as a eLearning module.
