From the options of grammar activities presented by Stanley, I would say that my top 3 are: 4.4 Questioning Infographics; 4.5 Grammar fight; 4.11 If only.
4.4 Questioning Infographics – this activity can be easily adapted to different levels and the selection of topics is broad. In addition, teachers can select infographics that discuss topics that are linked to students’ realities and up-to-date world issues to be discussed while practicing the desired language focus.
4.5 Grammar fight – This activity will encourage students to take a more active role while checking the veracity of the statements as well as they check sentence formation. It allows them to work collaboratively and discuss their reasons to consider the sentences true or false. One possible variation would be for them to create their own T/F statements about another topic or about themselves, in order to exchange with other groups or use a polling app/website to see who can guess the most T/F statements.
4.11 If only – Interesting and dynamic activity for them to engage with conditionals in context. Popplet seems easy and intuitive for classroom use. As a follow up activity, the teacher could present world event topics, such as: Brazil’s discovery, famous wars, the pandemic, etc., and ask students to choose one, search online for main facts and create another map with how things could have been different. They will incorporate reading and writing skills as they prepare their own short stories and practice the desired conditional while they make their second map independently.
