Consequences

Trying something new this week with the boys. I have been fighting with them to write neater, take their time on assignments and not scribble on color pages. They are 13 and 9 and they're homeschooler, theres no excuse. So, this week I decided to make them accountable for thier lessons and effort they put into it. There are rewards for good work and consequences for not so good work. They can earn things like a movie rental for "A" quality work all week and keeping up with their chores. And consequences, like spending their free time studying for poor work. (Depends on subject,etc) I have been trusting my oldest to do his math lessons then check his work and if he needs to redo a problem than he needs to rework it. He has been half ass doing his math. I went back a few lessons and found he has been doing half ass work, skipping the honors section, not checking the work he does and just copying answers for the rest. Lazy, lazy, lazy! I don't care how old he is, its not acceptable!
So, my oldest is now spending the weekend in his room studying the whoe time and re doing his math for the last few lessons. And this will continue until he shows improvement. If his handwritting gets worse he spend his free time in his room working on his handwritting.
I know it might sound mean but in PS he would have consequences for the work he has been turning in and just because he is schooled at home doesnt mean he should do half ass work and not have consequences.
I didn't believe in doing grades before but its something Im starting to use to grade thier work so they can have accountability for it.
This is gonna be hard!
