Work books ( 198 pages )

  • explain blocks,

  • plan and write algorithms,
  • execute and test the solution and then
  • reflect using Eduardo De Bono’s thinking hats.

Workbooks are available at www.textbooks4u.co.za.  Bulk discount and free training on Zoom for teachers who order our books for their classes. (English and Afrikaans copies available) 

Scratch video lessons on YouTube

The video lessons can be used to introduce topics and explain blocks in the classroom. 

Each lesson’s theme is unique to South Africa and learners are exposed to facts about STEM subjects like solar energy, wind energy, rainwater harvesting, and the SKA telescope.

In each lesson, a few new blocks are explained in Scratch, so that learners can use most of the blocks after these lessons. Lists, gaming blocks and even cloning of sprites and integration of Scratch with the micro:bit is covered.

The lessons can be used without the workbook, although learners will need notes to refer to and keep all planning and notes together and the work books make assessment easy.
