I used to be asked upfront to give work so “kids won’t get bored” .
I printed a small sheet saying something like
Dear xxxx I hope you have a lovely time on holiday.
Please keep a daily diary of all the interesting places you visit, remember to write about your experiences, draw pictures, stick in receipts for travel, meals out etc.
Look at the local currency, what pictures are on the bank notes, make rubbing of the coins.
What new foods have you tried? What did you enjoy the most.
Find out some of the history of the country and places you are visiting. Ask someone who lives there about a person who they admire who represents their country.
Learn how to say twenty words in the countries language.
Needless to say over many years I never got a single completed diary back. What most parents really wanted was a wedge of printed worksheets to dole out to shut the kids up on their all inclusive resort based holiday where they had little or no experience about being in another country.
I certainly never gave out work that we would be covering in school, they would not have understood my lesson plans and I would certainly not have wasted my time writing “bullet points” of what I was going to cover. I did make a note in exercise books though “ x was away on a family holiday from 15 June to 1 July.”
