Use your fantasy.
Ask your class.
Brainstorm with colleagues.
Or have a look at these ideas on how to use WHOWHATWHEREHOW cards.
Divide the players into groups of three or four and hand out a card to each group. Tell them how many cues they need to use in their scene. All of the groups prepare their scene. After each performance the audience guesses which WHO, WHAT,WHERE and/or HOW they’ve recognized.
On the internet there is an overload of improv forms. You could ask your actors or audience just before the improv for a WHO/WHAT/WHERE and/or HOW, you could also use Drama Nerds cards.
FORBIDDEN WORD - describing words
Split the group into two teams. Player 1 of team A describes one of the cues on a card without using the word itself or parts of the word. Team A tries to guess what he or she means. You could choose one of the categories (WHO WHAT WHERE or HOW) but it’s also possible players have to describe all four words on one card. Players of team A alternate turns and after three minutes it's team B's turn. The team who guesses the most words wins.
SHOW ME - body language
Split the group into 2 teams. Players are not allowed to talk - now they have to use their bodies to get the cue across. Team A guesses the words. Players of team A alternate turns and after three minutes it’s team B’s turn. The team who guesses the most words wins.
WHO WHAT WHERE HOW AM I? - closed-ended questions
One player quietly reads a cue from one of the cards. The rest of the group is allowed to only ask closed-ended questions. The player only answers yes or no. The group has to guess who, what, where or how the player is.
Split the group into two teams. Pick a category and have player 1 of team A start drawing what's on the first card. As soon as team A guesses the correct word, player 2 starts drawing and go on like this until 3 minutes are over. Count the cues that were guessed correctly. Now it's time for team B.
THE ODD ONE OUT - reasoning
Split the group into smaller groups of four and show the same card to each group. All groups have to think of which of the four cues on the card do not belong to the other three. The four cues on 1 card are not related in an obvious way, so all answers are correct. It’s all about the reasoning!
Divide the group into pairs. Give a different card to each pair. Player A starts to tell a story and as soon as he or she uses one of the words on their card, player B continues the story ...and so on, until all four words have been used.
RELAY RACE - telling stories
Divide the group into pairs. Give a card to player A, player B is not allowed to see the words on the card. Player A makes up a story in which all four words occur. After that player B has to retell the story. You could even make a relay race and see how many words are left in the story after 4, 5 or even 6 players.
Use the cards for all kinds of writing exercises. The only W’s that need to be added are WHEN and WHY!
