This activity has numbers with options of adjectives with either (m) for masculine, (f) for feminine, and (?) for unable to tell. As the teacher, randomly select which adjective you will say and whether it is masculine or feminine. Use gender-neutral names in a sentence for students to listen for a masculine or feminine difference, if it exists.
For example, if you say "Dominique est sportif", the student should choose "athletic (m)".
