Year 7 Vocab lesson

I am due to teach part of a class in a few weeks on food and plan on teaching the class some food-related vocab.
How many items do you think it's reasonable to try to teach in one lesson?
I started with 10 but am second-guessing myself that it's information overload. Any feedback would be appreciated on this...

 

I hate teaching the topic of food as the list is never-ending. I tend to intro the top 10 that are in the book and teach them the language to go with it (e.g.: I would like / I ate / the vs some vs a etc). I then give them a vocab list to stick in with lots of other food items on for them to refer to if they want to mention other foods (especially when talking about what they like to et etc)

 

Miller's Law suggests that the number of objects an average human can hold in working memory is 7 ± 2.
So nine for the most able and 5 for the least able is a general rule of thumb.

 

You could use a ton of cognates, too, I suppose...

 

This sounds exactly along the lines of what I was planning, so nice to hear someone else on the same wavelength, thank you!

 

A list with lots of items on? Is this for teaching French? Is the pronunciation of all these other items taught? Not meaning to be funny here but these are year 7s...what could possibly go wrong?

 

They learn the ones covered in the unit as required. The list is for info and a good way for them to independently practise the phonics work we do. Of course we do the necessary key work for them to be able to pronounce the words!
