Actividad 1 1 Diseño de estantes

Summary

The tutorial introduces Activity 1.1, in which students begin developing ideas for a circular shelf using GeoGebra. The goal is to explore and communicate a possible design—not to create a final construction plan or find one “correct” design.

GeoGebra sketching process

1. Prepare the workspace by making sure the grid is visible.
2. Locate the tools needed for the sketch, especially:
   • Circle, to represent the shelf’s circular shape.
   • Point, to set the circle’s center and a point on its circumference.
   • Segment, to draw possible structural pieces.
3. Draw a circle by choosing its center and a point on its circumference.
4. Draw a segment from the center to the circumference and identify it as a radius.
5. Add other segments to explore possible shelf supports or compartments.
6. Optionally, apply colors to different segments to make the sketch easier to interpret.
7. Treat the result as an initial idea that can be changed to suit the team’s preferences and functional needs.

Design and construction considerations

One suggested concept is a shelf that resembles a wheel and rotates, allowing books to be arranged inside and retrieved by turning it. Consider whether the design would be practical and how its depth or back space could keep books from falling out.

In a notebook, work with the group to answer:

• How would you begin building the shelf?
• What materials could you use?
• What tools would you need to measure and mark the pieces?

Record and justify the group’s decisions. The activity connects geometry to the design of everyday objects and values proposals that can be explained and defended.
