Algorithms are a relatively new concept to Computer Applications Technology teachers and learners, in IEB schools anyway. It is included in the Subject Assessment Guidelines document for Grade 10.
I decided to create a content pack for teachers and learners, covering algorithms. It consists of interactive PowerPoint presentations, two videos that I made, templates and tasks. I have included everything in a download in my 'shop'.
If you would like to purchase this for yourself and your learners, go check out the product page.
Here is video trailer which should hopefully give you more information.
