There is a practice to assess making colors agree, a crossword for vocabulary drill, and expressions for playing Uno. I play Uno after learning numbers and colors and have students in groups of 3 or 4 with their own deck. They may only speak in French. As they lay a card down, they identify it in French (cinq rouge). After 10 minutes, I'll switch it up and say that now we will practice the feminine form of the colors.
