Abstract
The theory of Teaching for Abstraction was used to construct a unit for teaching percentages in Grade 6. The unit focused on percentage as a multiplicative relationship and put more emphasis on why percentages are used than on how they are calculated. Analysis of the data collected showed that many students did learn to apply percentages meaningfully, although the level of achievement was not as high as expected. It was found that the Teaching for Abstraction approach provides many challenges for students and teachers, but is worthy of further research.
