# Creating a Proportional Replica of Aileron for a Display

Length:  Two 90-minute class periods

In the spring of 2012, the Aileron sculpture was installed in McCabe Park. This is the former location of the McConnell airfield. The sculpture represents the biplane of the early 20th century. It was fabricated by artist Michael Dillon using traditional blacksmithing techniques and tools that were used in the manufacturing of railroad equipment—another historic reference to Sylvan Park.

In this Mathematics Lesson, students will:

• The students will compae ratios of fractions to help create a proportion
• The students will use be able to recognize and represent proportional relationships.
• The students will demonstratw their understanding of proportional relationships by creating a table and/or graph and exlaning their rationale for proportinality based on evidence from the table and/or graph. The students will be able to discuss directly proportional relationships.
• The students will demonstrate their understanding of proportional relationships by identifying the constant of proportionality (unit rate).
• The students will e able to explain the proportional relationships of the pictures in Task 1 based on their graphs.
• The students will be able to explain the proprotional relationship of the sculptures in Task 2 based on their graphs.
• The students will create a scale drawing of a created artwork. The students will use the drawings to create a sculpture that has proportional dimensions.
