Just a few ideas on how to use WHOWHATWHEREHOW cards......
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/30 seconds To practise 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 To practise 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? To practise 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.
Outsider To practise 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!
Storytelling To practise telling stories
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 To practise 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.
Writing To practise creative writing
You could use the cards for all kinds of writing exercises. The only W’s that need to be added are WHEN and WHY!
