Food related idioms in teaching english vocabulary

BALDERDASH

The original Balderdash is a board game in which obscure words are read allowed,and players have to first propose a meaning,then have to guess the true meaning.We can take the concept and apply your own expressions-idioms,in this case.

Here is how it works:

The teacher reads aloud an idiom,one that that the students have not heard before.

Without discussing it,each of the students writes down a possiple definition on a note card.Students should aim for something plausible,as it increase their chances of earning points.
Simultaneously,the teacher down the real definition on a note card(ideally using casual language that matches the students).
The teacher collects all answers,shuffles them,and reads them aloud.
Each student selects which answer they believe to be the correct one.
The teacher adds up the scores:
1 point goes to a player for every other student who incorrectly guessed their
definition.
2 points go to a player for guessing the correct definition.
3 points go to a player for writing a definition that is very similar to the true
one.
If multiple answers are similar, you can combine them into the same definition when you read them aloud (and all players who wrote those similar ones receive equal points when others guess theirs).Also,you might choose to allow some discussion leading into step 5;students can voice which answers they like an which they do not,and they can try to cleverly convince others that their false answer is the correct one.
Balderdash is not only fun because of how silly it can get, but also it helps students remember the definitions later.They might remember it because it surprised them,or they might remember it because they will also remember the ridiculous false definition as well.


WORD CLOUD

While the previous way starts with the term and prompts students to guess the definition,the Word Cloud method starts with the definition and prompts students to guess the wording.

Suppose you have a group of idioms that thematically-as in food idioms,body idioms,etc.-as that is often how they are grouped in books.Take all the individual words from these expressions and scatter them in a word cloud(a visual pile with no distinctive pattern).You can make one online, or you can just write them on the board.I would recommend making the determiners and prepositions smaller than the rest of the words.You might also want to use different colors for different parts of speech.
Once all the words are displayed and students understand the context(also make sure they are familiar with each of the words),read out to them the definition of one of the idioms.The students then have to guess the phrasing of the phrasing of the idiom.Depending on the skill level of your class,they could discuss it and come up with an expression together, or they could individually write down their guesses and compare them afterward.
Their guesses should not be a shot in the dark.Many idioms make sense in the original context,but what makes them idioms is that hey tend to be applied to other contexts.So if students are given both the original context and the extended meaning, they should be able to produce expressions that match or at least are pretty close.
