Activity to introduce students to common German first names. Starts with a look at German names that are similar to English names. Continues with a discussion of how first names are typically associated with a gender. Ends with a list of German names. For each name, students guess whether they think it's a girl's name or a boy's name.
I usually do this during the first few weeks of German 1, right after students learn the er/sie forms of verbs and as they learn the words Mädchen and Junge. For each guess, they can say "Das ist ein Mädchen/Junge!" Great for reinforcement of these forms!
