Amber, I would have to read up on your posts!
A great use of your time, MUM.
But in case you have other things to do with your time, a précis: teacher and parent, do not like children to waste time on school work when they are at primary age. Set them free, don't stretch, don't challenge, let them set their own challenges through their play, let them self-direct and have lots of fun. Set yourself
free from worrying whether they are level this or that, top table or bottom, working 'to their potential' or not. Let them be happy and learn about the big, big world outside the school gates if they have extra creative energy after a day cooped up in there. Show them that Maths and English are but a tiny fraction of what is worth learning in this world. Get them to level 4 in Year 6 - any higher is unnecessary* . As long as they can access the secondary curriculum when they get there, job done imho.
Plays out well on a forum like this.
I am a creative irritant, I think. I help others feel secure in their opposite opinions
*unless you live in Bucks and they don't make the 11 plus cut the first time, in which case level 5s will buy you a ticket into the re-sits at 12.
