You would teach English in different classes and maybe in different schools every day from 7.30 to 12.30. The number of pupils in a class varies from 5 to 50 and the ages from 5 to 15 years old.
You will be free during the afternoons and the weekends. But depending on your place of stay and on your will, you may participate in local projects (handycrafts, computers, library, hair-dresser,… ) and you may organize any kind of activities with your contacts there.
The parents may also ask you to teach them English. Depending on the people you will meet, on your motivations, you may also teach English during the afternoon to the parents.
Be aware that being in front of 40 pupils that do not speak your mother tongue can quickly turn into a mess. You would be hosted and fed by a family throughout your stay in the province of Chimborazo. The living conditions are not those that we can know in North America or in Europe.
