Real and model dinosaur skeletons Added by Kadie Armstrong on Feb 6, 2008 An interactive animation demonstrating a scaled model version of a dinosaur skeleton.
Enlargement in Two Dimensions - Wolfram Demonstrations Project
This Demonstration allows you to explore some of the features of enlargement, also called expansion or dilation, in two dimensions. You can drag or add locators to change the shape of the object. You can also see the lines joining vertices to their images. This Demonstration is designed as a class activity, so by projecting the image on a whiteboard or an interactive board, students can demonstrate their skill by predicting the position of any hidden object. <p style="text-align:right;color:#A8A8A8"></p>
Enlarging by a scale factor
Enlarging by a scale factor Added by Kadie Armstrong on Feb 6, 2008 An interactive animation illustrating the process of enlargement by an arbitrary scale factor k. Click the numbered buttons to view the steps required to enlarge the triangle. This resource is from the unit What is Enlargement which is part of Absorb Mathematics . Free maths games
Scaling and area Added by Kadie Armstrong on Feb 6, 2008 An interactive animation showing the relationship between enlargement and area.

Enlarging a square
Enlarging a square Added by Kadie Armstrong on Feb 6, 2008 An interactive animation showing the effect of enlarging a square has on the square's area.
Scaling by a factor of 3 Added by Kadie Armstrong on Feb 6, 2008 An interactive animation showing the effect of enlarging a square has on the square's area. The square is scaled by a factor of three and the larger square shown to have nine times the area. Click the numbered buttons to reveal the steps.
