This game is played like traditional pictionary, with two teams. Each team has 1 minute to draw a concept on the board. They win a point if their team gets it. After the minute is up, the other team has one chance to steal the point. I also add some additional rules, like if they don't know the word they can pass to a team-mate. If they still don't know, the other team can choose to take that clue and it's worth double if they attempt it (considering the clue is likely one that will be difficult)
Place terms in a box so that team members choose randomly.
