Description: Topics and attributes are linked by subordinate relationships.
Uses: Group items (things, people, places, events, ideas, etc.) into categories.
- What items do we want to put together or classify? Top tier. How can we put them into groups that are alike? Second tier. Develop a rule to describe the group as to why they are alike. Are there any items that do not belong? If so create another group. (third tier)
- Repeat process until all items are classified.
Suggestions: Initially students can either free associate items then begin to group or start with one major item and add links. Using tiers or rows helps the student to visualize classifying and breaking items into categories.
