The Dictionary Game
First, split the chanichim into either teams or individuals. The leader then chooses a word from the dictionary (e.g. apple). Each team/individual then writes down a definition for the chosen word on a piece of paper and gives it to the leader. For example, one person may write "A crunchy fruit that grows on trees, often red or green in colour". The leader also writes the actual dictionary definition of the word on a piece of paper. Once all definitions have been handed to the leader, the leader will read out all the definitions one at a time. Each person then guesses which of the definitions read out is the actual dictionary definition. If someone guesses that your definition is the actual one, you receive one point. If someone guesses the correct definition, then they receive one point. After as many rounds as you like, whoever had the most points wins.
You can do this as a trigger activity by choosing only words related to your programme.
