Another silly arm-waving/cheerleading game.
Students use their arms to show M or F (whole-body F!) to indicate whether a word is masculine or feminine. Fun for introducing new vocabulary, you could do this at the same time as repeating for pronunciation, or afterwards as a recap.
Good for reinforcing constructions where the gender is not immediately obvious, such as les magasins, or for words that break rules, such as la mano in Spanish.
Could be expanded for plurals and singulars, probably with more energetic s-shapes for plurals or similar.
