El objetivo es relacionar el concepto de la semejanza y proporcionalidad con la operación multiplicación.
Es una construcción muy sencilla, rápida de hacer, con muy pocos pasos simples, muy adecuada para que la realice el propio alumno; a pesar de su sencillez, contiene una alta riqueza didáctica.
Permite realizar cuestiones de diversa índole, tanto en el proceso de construcción como en la observación y manipulación de la construcción realizada.

|
The files are technically sound and easy to open |
| |
|
The content is mathematically sound and usable in the classroom |
| |
|
Translation of the mathematical activity into interactive geometry is coherent |
|
|
The math and the figures are related | |
|
|
The figure is behaving consistently within the activity | |
|
|
The figure shows no ill effect | |
|
|
The numerical values (angles, lengths) are consistent | |
|
|
Functionalities and specific behaviors like sliders, keyboard interaction or macros are well described | |

|
In this resource, Interactive Geometry adds value to the learning experience |
|
|
I can produce drawings which are clear and sharp | |
|
|
Different configurations are easily produced | |
|
|
Helps the user to explore, experiment and conjecture | |
|
|
Conjectures can be visually validated | |
|
|
Different representations can be compared | |
|
|
Leads to understand geometric relations rather than numerical values | |
|
|
The activity can not be transposed to paper and pen | |
|
|
Interactive geometry helps reaching the pedagogical goal | |
|
|
Dragging around, you can illustrate, identify or conjecture invariant properties | |
|
|
Dragging around, you infer dependency relations among objects | |

This activity helps me teach mathematics |
| |
|
I know how to set my class for this activity |
| |
|
I found easily a way to use this activity in my curriculum progression |
|
|
The activity benefits later in the classroom | |
|
|
The activity relates easily with my usual teaching | |
|
|
It helps to understand the mathematical notions at work | |
|
|
The experiments they made provide an introduction to the next topic | |
