# VIC: String Art

by David Tynan

#### Objectives

• Introduction/revision of linear functions by manual construction of line equations from a pair of points
• Focus on use of patterns in lines used to create a ‘string art’ design
• Consideration of transformations of a 1st quadrant solution to create a complete ‘circle’
• Challenge questions for changing the design created

#### Vocabulary

• linear function rule
• function graph
• transformation
• variable and parameter

#### About the Lesson

Watch Activity Tutorial

This task provides a creative way to reinforce linear function algebra with Years 9–10 students and to learn about transformations of sets of such functions. The focus is on the students discovering what effect each parameter in the function (e.g. gradient & y-intercept) might have on the shape and location of the set of graphs.
