I got this project from the Santam art teachers manual. The lesson began with a look at architecture from around the world and a discussion around the different forms. The learners then chose a culture they liked best (out of a selection of about 5) and began designing their buildings.
The end result they were going for was a pop up artwork where the learner created 3 main buildings which popped off a flat but beautiful landscape. This years grade 6 group is very creative and always do something which surprises me.
