I think you are right when you say you don't want to overload them with stress; but be honest, who's the more stressed you or the children?!! I personally think it's almost too late now for any last minute cramming - we're going to do a little bit of revision to tie up a few loose ends from last term but it will be very low key and relaxed. They know if they have any specific questions they can ask me but we're very much at the stage now where we all just want it over and done with so we can get back to normal! Then you can stop being stressed for a few months until the results are due! Year 6 is a great year to teach, SATs gets in the way and is a complete pain in the bum but we all get through it! Good luck, don't worry!!
