Trying to set up a simple display for Y2 to improve their writing but not too sure in my own mind of the different between openers and connectives? So, for example, the word 'because' could be both, simply depending on it's place in the sentence. And are connectives the same as 'joining words' / 'prepositions'. Current Y2 teacher has a list of what she calls 'joining words' which includes - after a while, during, after, meanwhile, before, because, unless, later, when .... Surely many of these are sentence openers? Help!
