My DS had terrible writing in Y5 and I spent money on handwriting lessons and did practice with him in handwriting books. Once he had passed the 11+ I relaxed, and now DS is in Y7 and has slipped back into terrible habits
I have bought the Andrew Brodie Handwriting Today workbooks, which seem to be much less 'babyish' than what we had last time and I am impressed with it so far. I have also bought a Lamy pen (not too pricey on auction site) which has also made an immediate improvement.
Early days, but hopefully this will get him back on track. I'm not after beautiful, would settle for legible writing.
