Students will first learn about scale factor as part of geometry in 7 th grade and continue to work with scale factor in high school. What is a scale factor? A scale factor is a ratio between two corresponding sides of similar shapes.
Lesson 1 Summary: What are Scaled Copies. Lesson 2 Summary: Corresponding Parts and Scale Factor. Lesson 3 Summary: Making Scaled Copies. Lesson 4 Summary: Scaled Relationships. Lesson 5 Summary: The Size of the Scale Factor. Lesson 6 Summary: Scaling and Area. Lesson 7 Summary: Scale Drawings.
Scale factor is a conversion factor - a number which is used to increase or decrease the size of a figure. For example, if a circle needs to be increased in size using a scale factor of 4, and the circumference of the circle is 7 units.
Identify the constant of proportionality from a table of values, and connect it to scale factor. Define scale factor as the value that all sides of a figure are multiplied by to create a scale image. Find the scale factor between two scaled images. Use a given scale factor to draw a scale image.
Define and determine scale factor between two scale images. Use scale factor to draw scale images.
In a scale drawing, all lengths are multiplied by the same scale factor. If the scale factor is greater than 1, the figure is expanded, and if the scale factor is between 0 and 1, the figure is

Aug 15, 2020 · Definition: Scale Factor. To create a scaled copy, we multiply all the lengths in the original figure by the same number. This number is called the scale factor. In this example, the scale factor is 1.5, because \(4\cdot (1.5)=6\), \(5\cdot (1.5)=7.5\), and \(6\cdot (1.5)=9\). Figure \(\PageIndex{4}\)
