I may not be doing everything right, but there is one thing that is working for me. I took the advice of some of those parenting magazines and set-aside a "working" space for each of my kids.
I love it!
They love it!
It is their place to color, write, read, doodle, whatever.
Here's a pic of them coloring at their respective tables this morning. The only trick to the whole thing is to have them keep their areas neat. If they can't find the table because of clutter, then they won't be tempted to use it to work on.
How are you getting your kids ready for school or homeschool?
