High schoolers observe the cracks in school walls and pavements. In this geometry lesson, students explore the factors to be considered before building a structure. They complete a graphing and calculation worksheet after the...

Find both the center and the scale factor of a dilation that maps a given figure to another one. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Investigate dilations using this interactive resource. Students are given an opportunity to explore how scale factors can be used to enlarge or reduce the size of a given figure. Be sure to follow the link to the printable activities,...

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to draw dilated figures in the coordinate plane and use dilated figures in the coordinate plane to find scale factors. Students...

[Free Registration/Login may be required to access all resource tools.] In this lesson students recognize dilations and use scale factor to determine measurements. Students examine guided notes, review guided practice, watch...

[Free Registration/Login may be required to access all resource tools.] This concept introduces dilations and how to find scale factors. Students examine guided notes, review guided practice, watch instructional videos and attempt...

In this task, students investigate a dilation of a line segment and how the length of the dilation relates to the scale factor. Aligns with G-SRT.A.1.

Oswego City School District provides a three link tutorial on dilations. By clicking on each of these links, you will find the definition of a dilation, examples of dilations, and a quiz to test your skills.

This site defines dilation and gives an example with a diagram. There is also an interactive activity involving a JavaSketchPad page in which you can explore dilations. In addition, be sure to follow the links to related terms, more...

[Free Registration/Login may be required to access all resource tools.] This concept explores graphing a dilation given a description of the dilation. Students examine guided notes, review guided practice, watch instructional videos and...

This site offers a very basic discussion of dilations. It explains what a scaling factor is and provides illustrations.

The goal of this task is to apply dilations to a triangle in the coordinate plane. Learners will need to find the coordinates of a point which cuts a given segment into one third and into two thirds. The two dilated triangles share a...

Get independent practice working with dilations. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

This lesson focuses on dilations, a dilation is a transformation that resizes a geometric shape, by making it bigger or smaller.

Find a clear explanation of similar figures. Discusses how they can be transformed through a sequence of rotations, reflections, translations, and dilations. Explanations are supported with illustrated examples.
