Exemplars (from the NaCCA curriculum)

Research, Collaborative learning/ Group work: With relevant resources engage learners in mixability groups to discuss sectioning and its relevance to the building industry.

Experiential learning, managing talk for learning:
1. Show to learners a model of a cross section through a domestic building showing all the sectional members
2. Instances where a model is not available, you may consider a virtual form.
3. Assist learners to identify the sectional parts discussed earlier on the model.
