The word transform means "to change." In geometry, a transformation changes the position of a shape on a coordinate plane. What that really means is that a shape is moving from one place to another. There are three basic transformations: Flip (Reflection) Slide (Translation) Turn (Rotation) Being able to visualize the movement of a shape is very important. The SMARTBoard mini-movies below show a letter, or a polygon (after all, block letters are really just polygons), in their original positions before being transformed. By clicking the play button, we are able to watch the path the letter takes while being transformed and see their ending positions after the slide, flip, or turn has taken place.

Part of the problem is that professional development, both pre-service and in-service, does little to build teachers' understanding of how their discipline is used, singularly and in combination with others, to help solve problems and innovate beyond school walls. It's the rare geometry teacher who knows how architects, carpenters, bricklayers, and tile setters use the 3-4-5 triangle in construction technology.
