I have two sons, 5(k) and 7(2nd), that have horrific handwriting. My 2nd grader was in public school up until this year and I feel like I am undoing a lot of negative techniques. My 5 year old is starting fresh, but not picking up on just copying the letters. What programs have worked for y'all? I have mainly been looking at Handwriting Without Tears and A Reason for Handwriting, but I cannot make up my mind. Any advice?
