The spontaneity when we speak English is very important, and we encorage them to speak without fears about the mistakes. They need to trust themselves.
However, it is important to remind them and keep in mind the basic structure in English with the subject verb and complements. Therefore, we have been creating different games and dinamycs to create sentences in order to choose the right elements in the right order.
Cards, basketball, contests....are some of the elements that we are using to make grammatical issues a little bit more attrative to learn.
