Quiz your knowledge of Russian vocabulary. You do not need a partner for this exercise. Make sure all the cards are stacked with the question side up. Start going through the cards one by one. The question side will might ask something like, "How do you say 'Hello' in Russian?" Before you flip the card over, try to pronounce the correct word. Flip it over after you've answered the question to see if it's right.
Quiz with another friend. Take turns having one individual ask all the questions while the other individual answers everything. Make sure the individual answering the questions cannot see the bottom of the card. If the individual gets the question wrong, help them learn by correctly pronouncing the right word.
Turn that quizzing of a partner into a game to make things interesting. Get a piece of paper and write down each player's name. Take turns answering the vocabulary questions on the flash cards. The first person to get five answers wrong has to take a turn of "Truth or Dare." This way you'll keep the studying lively, entertaining and fun.
