Last week 8 year old dd had to write a list of words with a silent k. I thought that was ok homework as dd was able to use her dictionary to write the list - given all the words start with a k.
This week it's the silent L - and actually, it's not that straightforward.... And I say that as a highly educated professional who writes every day!
We looked on the internet and there are some words which are listed as having a silent l by some sources, where the l is now actually pronounced by some people - balm, palm, calm, almond....
Anyway, dd and I had an interesting discussion about this, but I don't think the teacher really thought this out!
