Instructional Ideas

• Allow learners to bring their own building materials to create more complex structures
• Once complete, have the class order the structures from smallest to largest

Classroom Considerations

• Allow time to collect and prepare materials prior to the activity
• The first of a five-part series of lessons comparing macro and micro
  

Pros

• Offers extension ideas to continue the lesson 
• Highlights key vocabulary

Cons

• None
