This workbook is designed with two main focuses:
Conceptual focus: To guide learners to understand stoichiometric concepts at submicroscopic, macroscopic and symbolic levels
Calculation focus: To guide learners to solve stoichiometry questions, largely using the unit factor method
 
Some features of this workbook: 
thinking, understanding, use of proportion, calculation competence and terminology-acquisition are focused on.
its systematic, guided and consistent colour-coded structure is intended to guide learning even if a teacher or other resources are absent by: (1) giving worked examples, then (2) providing guided practise, then (3) removing support to develop independent competence.
the laminated version can be used in a write-and-wipe manner with whiteboard markers.
