LEARNING OBJECTIVES
  • Utilizzare strumenti geometrici: Imparare a usare correttamente riga, compasso, squadra e goniometro per eseguire costruzioni geometriche precise e accurate.
  • Sviluppare abilità di disegno tecnico: La costruzione di un ennagono richiede abilità di disegno tecnico, come la tracciatura di linee rette, la realizzazione di angoli precisi e la creazione di simmetrie.
  • Potenziare la precisione e la cura del dettaglio: La costruzione di un ennagono richiede precisione e attenzione ai dettagli, elementi fondamentali per la realizzazione di un disegno geometrico corretto.
  • Introdurre concetti di base della trigonometria: La costruzione di un ennagono può essere un'occasione per introdurre concetti trigonometrici basilari, come la definizione di seno, coseno e tangente di un angolo.
Activities

Materiale occorrente: Procurarsi i seguenti strumenti:

  • Foglio di carta A4 o cartoncino
  • Riga
  • Compasso
  • Matita
  • Gomma
  • Penna nera (opzionale)

Consigli:

  • Per ottenere un disegno più preciso, è consigliabile utilizzare strumenti di alta qualità e tracciare linee sottili con la matita.
  • È possibile utilizzare una calcolatrice per determinare la misura del lato dell'ennegono, in base al raggio del cerchio disegnato.
  • Per verificare la correttezza della costruzione, è possibile controllare che tutti gli angoli interni dell'ennegono siano uguali e che tutti i lati abbiano la stessa lunghezza.

Has the sequence didactic sense?

Well sequenced, following some sort of didactid order: starts from the alumni ideas and augments both in completeness and abstraction level. For instance, following the learning cycle, inquiry cycle, modeling cycle, ABPs structure...
