School spelling lists

Of course they're not interchangeable, unless you approve of robbing the English language of its superb ability to be able to express ideas in writing with precision and clarity so that readers don't have to perform mental gymnastics to extract the meaning of what is being expressed.

Practise is what you do, practice is the institution you do it in.

I'm afraid the recently popular (i.e in the 1980s and 90s) belief that anything goes so long as people can 'make meaning' from it has not been a Good Thing for our written language. But don't blame the poor teachers who were themselves taught by this philosophy.

A lot of teachers are very good at their jobs but unfortunately seem not to have been taught English grammar very well. The current system appears to be putting more emphasis on it, particularly at primary level. Maybe the next generation will be better.

'Practice' and 'practise' are not interchangeable. The first is a noun, the second a verb. It's just another example of creeping Americanisms. When I did proofreading for non-native speakers of English (university students) I had to explain to them that UK English and American English are different. They'd been taught the latter and didn't know there was a difference. Presumably a lot of native English speakers don't either!

Yes, ixion, exactly! I'm probably being far too fussy. It should also be, 'please practise.' I think the 'practise/practice is generally not understood, but the school is in an affluent area with many professional parents who would spot these errors immediately,

Class dojo is American or originated there at least. But I think OP is saying that the instructions came via the teacher? Current spelling list in a school I am involved in includes practice/practise and the difference between the two.

Is ClassDojo an American company I wonder?

No they are not interchangeable.

I'm a qualified primary teacher.
Many teachers do have poor grammar and spellings.

The thing with primary teachers is that they are expected to be good in all subjects.

My weakness is maths. I admit that I am not up to teaching year six maths at all.

Here are this week's spellings?
