Discovering Phi: The Golden Ratio

Each group needs:

• ruler
• pencils
• calculator
• laminated Fibonacci squares puzzle made from poster board (use the Squares Puzzle Template (PDF))
• Brainstorming Squares (PDF), one copy per pair of students
• Math Adventurers Worksheet (PDF), one copy per pair of students

To share with the entire class:

• several laminated copies the three-page Natural Pictures (PDF) attachment, enough so each group can have at least one picture at any one time

For the robot teacher demonstration:

• LEGO EV3 kit (buildable and programmable robot), available at https://shop.lego.com/en-US/LEGO-MINDSTORMS-EV3-31313, $349.99, with robot constructed and programmed as in The Fibonacci Sequence & Robots activity
• large sheets of paper
• tape, to secure paper to the floor and a marker to the robot
• marker

Note: This activity can also be conducted with the older (and no longer sold) LEGO MINDSTORMS NXT kit instead of EV3
